Add support to pass build flags while compiling Linux kernel.
This change is required to add support in Linux kernel to use external
host executable. (example: dtc)
Usage example:
TARGET_KERNEL_MAKE_ENV := DTC_EXT=dtc$(HOST_EXECUTABLE_SUFFIX)

SPI core has a characterstic that it always sends data in FIFO word size
when we compress the data and fill the FIFO. This helps to improve the
overall througput but sometimes for the data transfers which is not
aligned to FIFO Word [i.e 4] it pads extra bytes and sends out which can
mislead spi slave device.
Do not enable packing if it's a FIFO mode transfer and data size is not
aligned to FIFO word size.

In the current implementation, the timestamp buffer is mapped at
the beginning of the first rotator session, and unmapped during
the rotator device remove. In sdm 660/630, there is no separate
context bank for rotator. In some cases (like secure display),
the IOMMU might be detached and reattached, invalidating the
timestamp buffer map.
Changing the timestamp buffer implementation to map/unmap for every
rotator session instead of rotator device create/remove, to handle
such cases.

During clock gating (ufshcd_gate_work()), we first put the link hibern8 by
calling ufshcd_uic_hibern8_enter() and if ufshcd_uic_hibern8_enter()
returns success (0) then we gate all the clocks.
Now let’s zoom in to what ufshcd_uic_hibern8_enter() does internally:
It calls __ufshcd_uic_hibern8_enter() which on detecting the LINERESET,
initiates the full recovery and puts the link back to highest HS gear and
returns success (0) to ufshcd_uic_hibern8_enter() which is the issue as
link is still in active state due to recovery!
Now ufshcd_uic_hibern8_enter() returns success to ufshcd_gate_work() and
hence it goes ahead with gating the UFS clock while link is still in active
state hence I believe controller would raise UIC error interrupts. But when
we service the interrupt, clocks might have already been disabled!
This change fixes for this by returning failure from
__ufshcd_uic_hibern8_enter() if recovery succeeds as link is still not in
hibern8, upon receiving the error ufshcd_hibern8_enter() would initiate
retry to put the link state back into hibern8.

CPU hotplug operations take place in preemptible context. This leaves
the hotplugging thread at the mercy of overall system load and CPU
availability. If the hotplugging thread does not get an opportunity
to execute after it has already begun a hotplug operation, CPUs can
end up being stuck in a quasi online state. In the worst case a CPU
can be stuck in a state where the migration thread is parked while
another task is executing and changing affinity in a loop. This
combination can result in unbounded execution time for the running
task until the hotplugging thread gets the chance to run to complete
the hotplug operation.
Fix the said problem by ensuring that hotplug can only occur from
threads belonging to the RT sched class. This allows the hotplugging
thread priority on the CPU no matter what the system load or the
number of available CPUs are. If a SCHED_NORMAL task attempts to
hotplug a CPU, we temporarily elevate it's scheduling policy to RT.
Furthermore, we disallow hotplugging operations to begin if the
calling task belongs to the idle and deadline classes or those that
use the SCHED_BATCH policy.
