Move usb_icl_votable creation and it's callback in the
battery.c file, in preparation for an upcoming change where
usb_icl_votable callback will be able to
disable parallel charger when a low input current
request is set.
The new callback uses CURRENT_MAX property to be set on main
psy to set the ICL limit of primary charger.
The limit setting code in main charger path where the votable
call resides currently relies a lot on client being present or not.
Since the votable is being moved away, it won't have information
about the client. So use the current parameter of INT_MAX to
indicate no clients present.
Also it could be that main psy is not instantiated by the time first
icl vote comes in. Ensure that we rerun_election on usb_icl_votable
the instant main psy is seen.

The charger driver ensures that parallel charging remains
disabled as long as AICL is below threshole (1400mA) using
it's software voting mechanism(USBIN_I_VOTER), thus disable
hardware's autonomous control of input current based parallel
charging.

Currently, the driver enables parallel charger as soon
as a favorable charger is seen. This causes many, unnecessary
splits of AICL results as AICL runs for the first time. Besides
the detection logic could further update charger type and rerun
AICL.
Its best to simply delay enabling parallel charger for 30 seconds.
This ensures that type detection and its AICL run to completion and
parallel charging starts with a stable AICL result.
To realize this
- implement a workqueue which will be scheduled/cancelled 30 seconds
later when vbus plugin interrupt happens.
- The workqueue signifies that 30 seconds have elapsed and parallel
charging should be enabled by PL_DELAY_VOTER.
- remove PL_DELAY_HDVP_VOTER since PL_DELAY_VOTER will
ensure parallel gets enabled after 30 seconds of insertion.
- unvote from PL_DELAY_VOTER only when the typeC removal event happens.
A PR_SWAP during a sink session will keep the PL_DELAY_VOTER's vote
enabled, we expect CHG_STATE_VOTER to disable parallel since device will
be supplying VBUS and not charging the battery. This also means that
when another PR_SWAP happens and the device starts operating in sink mode
again, PL_DELAY_VOTER's vote will remain enabled and parallel charging
would begin when other conditions become favorable. IOW PL_DELAY_VOTER
tracks 30 second after physical insertion and remains unaffected by
PR_SWAPs.

The current code enables parallel charging if a high voltage
charger is seen (QC or PD) or a high current charger is seen.
This means that parallel charger could remain enabled when PD
transitions its voltage even though it has reduced the current
to 500mA. It is desirable to disable parallel charging during
such voltage transition.
So prepare for this change by first ensuring that only a QC
charger votes for USBIN_V_VOTER. The PD charger, even while
operating at higher voltages will need to depend on USBIN_I_VOTER,
just like a simple DCP charger, to enable parallel charger.

Runtime PM reference count is being increased in mmc_claim_host() and
is decreased in mmc_release_host(). This reference count is kept
during the complete cycle of a claim -> release host.
Same need to be done even in mmc_try_claim_host() as well. Increase
the runtime PM reference count by invoking pm_runtime_get_sync() from
mmc_try_claim_host() upon first successful claim.
Without this change the runtime PM reference count goes for a toss
since count is not getting incremented in mmc_try_claim_host() but is
getting decremented in mmc_release_host().

commit 165a5e22fafb "block: Move bdi_unregister() to del_gendisk()"
added disk->queue dereference to del_gendisk(). Although del_gendisk()
is not supposed to be called without disk->queue valid and
blk_unregister_queue() warns in that case, this change will make it oops
instead. Return to the old more robust behavior of just warning when
del_gendisk() gets called for gendisk with disk->queue being NULL.
