Making the "WFI wait" from interruptible to non-interruptible. This is
done because there is a probalbilty between the thread making a call to
nvadsp_os_suspend / nvadsp_os_start getting signaled or having a
pending signal before ADSP enters WFI and the CPU getting the WFI
interrupt.This results in wait_for_completion_interruptible_timeout()
returning -ERESTARTSYS, due to which nvadsp_os_suspend treats it as
failure although ADSP has entered WFI and the WFI interrupt has been
received on the CCPLEX.
Since this is a race it is not seen often.
Also, reducing the timeouts for WFI and logger wait to 800 and
500 ms respectively. The timeouts have been reduced because during
suspend there are only a few register writes and logger has been
reduced from 1 MB to 16 KB.

freq, update it in adsp os args from ccplex-adsp shared
memory. This adsp freq update is needed by EDF scheduler
for scheduling EDF threads. The EDF scheduler gets
current adsp freq from shared memory instead of

However, for APE1 (i.e. chips = T21x), timer prescalar
must still be updated through mailbox each time adsp cpu
freq is changed.

When ADSP OS is loaded from adsp.elf, it loads two sections : adsp os
and the vector table. The vector table is copied to a local buffer
before writing to the EVP registers.
There is a probability that, if the adsp.elf is hacked / modified by
an attacker, it can write to other APE register spaces. Hence, the
destination address obtained from the elf is checked with evp base
before copying.
Also, this fixes out of array-bound writing to evp buffer.
