Common Clock Framework(CCF) already has a clock ops hook `debug_init` which
could be used for the debugfs clock measure functionality. Remove the APIs
from the CCF and update the 'debug_init' clock ops to the clock types which
require the measure functionality.

The 'measure' functionality is a debug feature which allows the user of
clocks to allow measuring the frequency of a given clock using the ring
oscillator.
Move 'measure' code to a new clk-debug file to support the functionality.

Change the initcall level of qpnp-misc driver from module_init()
to subsys_initcall() so that the misc devices can be available
earlier. This helps the clients to access the registers under
misc peripheral sooner without a probe deferral.

While in DRP the legacy cable detection may fail. When a legacy cable is
detected the legacy input current limits are enforced by hardware.
Always assume a legacy cable since the legacy cable detection will
fail in some cases. Manually enforce the legacy input current limits to
ensure USB stability and compliance. As a side effect, non-legacy 22k
ohm and 10k ohm Rp adapters will be current limited to legacy standards.
To realize this:
- Set a limit of 100mA as soon as type-c is connected and remove that
limit once PD is confirmed.
- If PD is not confirmed:
- SDP: Use 100mA vote until USB PHY updates it to 500/900mA
- CDP: Use 1.5A vote
- DCP: Use 1.5A vote
- HVDCP: Use 3A vote

While in DRP the legacy cable detection may fail. Legacy cable
detection is essential to preventing CC OV damage.
Always assume a legacy cable since the legacy cable detection will fail
in some cases. As a side effect, non-legacy HVDCP adapters will stay at
5V if they have a 10k ohm Rp.
To realize this:
- Remove disallowing PD based on the legacy bit being set. That bit set
or unset is not reliable and it is safe to try PD.
- Remove the workaround which tries to fix legacy cable being set
incorrectly at boot. That bit set or unset is not reliable.

Currently to override the ICL the self-clearing ICL override bit is
used. The problem with this bit is that it is self-clearing and a
separate register needs to be read to get the override status.
Furthermore, the hardware will automatically clear this bit on USB
removal.
A new ICL override bit was added in PMI hardware revision 2.0. This bit
is not self-clearing, and can be set prior to USB insertion. Use this
new bit.

Currently AICL will be rerun whenever PD requests a voltage increase.
While this works in most cases it can become problematic if PD requests
the same voltage twice, and the ICL may fall to ICL_MIN.
Since the voltage requests originate in the userspace it would be less
error prone to allow the userspace to rerun AICL instead. Do it.

When APSD_START_ON_CC_BIT is set both VBUS and CC must be attached
before APSD runs. This eliminates all issues related to slow plugin.
Unfortunately this means that if CC is re-asserted anytime after APSD
finishes, then it will rerun again.
Fix this by disabling APSD_START_ON_CC_BIT right after CC is asserted,
and enable it after USB removal.
