qseecom_send_modfd_cmd converts ION buffer's virtual address to
scatter gather(SG) list and then sends them to TA by populating
SG list into message buffer. As the physical memory address in
SG list is used directly by TA, this allows a malicious TA to
access/corrupt arbitrary physical memory and may lead to the
process gaining kernel/root privileges. Thus, make changes to
have the QSEEComm driver passing a list of whitelist buffers
that is allowed to be mapped by TA, and the QSEE kernel, in turn,
should add checks to the register_shared_buffer syscall to make
sure the shared buffers an application is mapping falls within
one of these whitelist buffers.

On certains devices, some of the CPUs within the apps subsystem are not
functional and might be removed from the CPU possible map. To handle this
dynamic list of CPUs, sleep driver shouldn't make any assumptions with
regards to the logical mapping of the CPU.
Remove the assumption on how physical CPUs are mapped onto logical CPUs and
populate create a reference of sleep status driver in the corresponding
CPU phandles. When the sleep status driver is probed, it would probe
iterating the list of possble CPUs.

On some hardware, the display byte and pixel clocks can have multiple
parents and we can switch between them dynamically. To support this
add a new set of ops. Also implement the get_parent for these clocks
so that handoff code can dynamically set the parent for these clocks
instead of relying on the parent field to be set up explicitly when
definining the structures for those clocks. On hardware which does not
support dynamically switching parents, the old set of ops can still be
used.

mandated amount of time, record additional PLL debug information in the
kernel log and then panic.
