Fuzzing the PTI-x86-32 code with trinity showed unhandled
kernel paging request oops-messages that looked a lot like
silent data corruption.
Lot's of debugging and testing lead to the kexec-32bit code,
which is still allocating 4k PGDs when PTI is enabled. But
since it uses native_set_pud() to build the page-table, it
will unevitably call into __pti_set_user_pgtbl(), which
writes beyond the allocated 4k page.
Use PGD_ALLOCATION_ORDER to allocate PGDs in the kexec code
to fix the issue.

This reverts commit 77754cfa09.
The patch was necessary to silence a WARN_ON_ONCE(in_nmi())
that triggered in the vmalloc_fault() function when PTI was
enabled on x86-32.
Faulting in an NMI handler turned out to be safe and the
warning in vmalloc_fault() is gone now. So the above patch
can be reverted.

Random address can be set only if the instance is created which
is done in Set ext adv param.
Random address and rpa expire timer and flags have been added
to adv instance which will be used when the respective
instance is scheduled.
This introduces a hci_get_random_address() which returns the
own address type and random address (rpa or nrpa) based
on the instance flags and hdev flags. New function is required
since own address type should be known before setting adv params
but address can be set only after setting params.

Because the SPI controller deasserts the chip select when the TX fifo is
empty (which may happen in the middle of a transfer), the CS should be
handled by linux. Unfortunately, some or all of the first four chip
selects are not muxable as GPIOs, depending on the SoC.
There is a way to bitbang those pins by using the SPI boot controller so
use it to set the chip selects.
At init time, it is also necessary to give control of the SPI interface to
the Designware IP.

We queue an event for the next vblank in two places:
- armada_drm_crtc_atomic_flush() provided we aren't doing an

- armada_drm_crtc_commit() if we are committing a modeset.
This ensures that the event is sent at the correct time (after all
