input: tri-state-key: Use ffz() instead of find_first_zero_bit()
find_first_zero_bit() is intended for large bitmaps; ffz() is much faster
when only a single word needs to be searched through.

input: tri-state-key: Clean up some code styling
Use a macro to store the number of states, reduce the curr_state member in
the struct to uint8_t (since it only needs to contain 3 bits), and use
find_first_zero_bit() instead of a loop to find the first zero bit.

input: tri-state-key: Rewrite and optimize
A driver for such a simple device shouldn't be so ugly. Clean it up and
optimize it in the process.
Summary of changes:
-Remove unneeded switch device
-Remove unused/unnecessary struct members
-Remove module references (this driver will always be built in)
-Utilize fixed loops and clever logic to eliminate significant amounts of
code duplication
-Remove unused pinctrl code
-Use a threaded interrupt handler
-Process interrupts directly in the threaded interrupt handler (which runs
with realtime priority) rather than a worker
-Read the initial switch state upon init (so userspace gets the correct
switch state upon boot)
-Refactor code wherever possible to make it cleaner
Note that although the procfs naming scheme is non-standard (i.e.
"keyCode_top" instead of "keycode_top"), the old naming scheme is retained
in order to maintain compatibility with userspace.

A fixed sink PDO request includes both operating current and
max current. Although the max current requested may be greater
than the available source advertisement, as per spec only the
operating current request needs to be considered. The sink will
likely have also set the Capability Mismatch bit as well. Hence,
don't reject the request otherwise the sink will keep
re-requesting and never enter a contract.

Android has been benefiting quicker boot from bigger readahead during
boottime than runtime. However, the boottime readahead setting is set
when init is established after treble early mount. This patch will make
readahead bigger by default so early boot can benefit from it. Readahead
will be reset by init on boot_complete.

Change the VM_MAX_READAHEAD value from the default 128KB to a
configurable value. This will allow the readahead window to grow to a
maximum size bigger than 128KB, which greatly benefits to sequential
read throughput and thus boot performance.

In order to solve a problem with 802.11, the so-called hole-196 attack,
add an option (sysctl) called "drop_unicast_in_l2_multicast" which, if
enabled, causes the stack to drop IPv6 unicast packets encapsulated in
link-layer multi- or broadcast frames. Such frames can (as an attack)
be created by any member of the same wireless network and transmitted
as valid encrypted frames since the symmetric key for broadcast frames
is shared between all stations.

be created by any member of the same wireless network and transmitted

Additionally, enabling this option provides compliance with a SHOULD
