Currently, when a single channel's brightness is set, and then cleared
to zero subsequently, the LED stays on instead of getting turned off
because symmetrical brightness distribution logic does not allow the
paired channel's brightness to be set to zero. Fix this.
It was also observed that the brightness of a channel that is getting
turned off doesn't show up as zero, so fix that as well.
In addition, strengthen error-checking of the "qcom,led-mask" device
tree property.

To support SA8155, we need the following clocks:
GCC_GPU_CFG_AHB_CLK, GCC_DDRSS_GPU_AXI_CLK.

Due to a race condition between the probe and glink message
callback, it is observed that the glink messages/notifications
can be handled even after the probe failure which leads to
an invalid memory access. Fix it by introducing "initialized"
flag. While at it, add few error logs to identify the exact
message failures.

In certain devices, LED channels are paired and connected to two
separate LEDs. Due to symmetrical configuration, a switch that controls
all four channels sets the same brightness value to both LEDs, which is
not the intended behaviour; hence, handle this case separately.
E.g. If flash0 (group 1) is set to 144 and flash1 (group 2) is set to
1056, current will be distributed evenly to all 4 channels like so: 300
mA would be set on all channels (as 144 + 1056 = 1200; 1200 / 4 = 300).
Change this to:
144 / 2 = 72 on channels 0 and 3 (group 1)
1056 / 2 = 528 on channels 1 and 2 (group 2).

USB_CONFIGFS_RNDIS is currently enabled by gki_defconfig.
Although the upstream F_RNDIS driver can coexist with the USB
GSI driver, currently there is a conflict in userspace that can
result in choosing the wrong one. Disable the SW-only F_RNDIS
driver to allow the GSI driver to be enabled exclusively.

This reverts commit f85843d3df ("iommu/arm-smmu: Add support to disable
page-table coherency")
This change was added in order to allow iommu clients to disable page
table coherency.
However when page table coherency is disabled using this property on an
SMMU which is configured to be IO-coherent the attempts by the page table
code to apply CMOs on page table entries will be ignored because the
device it is using to apply the CMOs, the SMMU device, is IO-coherent.
This can result in the SMMU seeing stale page table entries.
Since this feature doesn't work and no clients are using revert it.
