A disable and unprepare is called on a clock which is voted for, but never
unvoted for. By disabling and unpreparing this clock, the clock state is
maintained the same across modem restarts.

A read of a register during the software fatal error handling is removed.
This read causes an unclocked access which prevents the modem subsystem
from succssfully restarting.

TX and RX FIFOs of Microcontroller are used to exchange commands
and messages between Micro FW and CPP driver. TX FIFO depth is
16 32-bit words, incase of errors there is a chance of overflow.
To prevent possible out of bound access, TX FIFO depth or
level is checked for MAX depth before accessing the FIFO.

A computation in update_top_tasks() is indexing

DEBUG_PAGEALLOC removes the valid bit of page table entries to prevent
any access to unallocated memory. Hibernate uses this as a hint that those
pages don't need to be saved/restored. This patch adds the
kernel_page_present() function it uses.
hibernate.c copies the resume kernel's linear map for use during restore.
Add _copy_pte() to fill-in the holes made by DEBUG_PAGEALLOC in the resume
kernel, so we can restore data the original kernel had at these addresses.
Finally, DEBUG_PAGEALLOC means the linear-map alias of KERNEL_START to
KERNEL_END may have holes in it, so we can't lazily clean this whole
area to the PoC. Only clean the new mmuoff region, and the kernel/kvm
idmaps.
This reverts commit da24eb1f3f9e2c7b75c5f8c40d8e48e2c4789596.

Resume from hibernate needs to clean any text executed by the kernel with
the MMU off to the PoC. Collect these functions together into the
.idmap.text section as all this code is tightly coupled and also needs
the same cleaning after resume.
Data is more complicated, secondary_holding_pen_release is written with
the MMU on, clean and invalidated, then read with the MMU off. In contrast
__boot_cpu_mode is written with the MMU off, the corresponding cache line
is invalidated, so when we read it with the MMU on we don't get stale data.
These cache maintenance operations conflict with each other if the values
are within a Cache Writeback Granule (CWG) of each other.
Collect the data into two sections .mmuoff.data.read and .mmuoff.data.write,
the linker script ensures mmuoff.data.write section is aligned to the
architectural maximum CWG of 2KB.

Create asm/include/sections.h to collect these definitions (and include

Literal loads of virtual addresses are subject to runtime relocation when
CONFIG_RELOCATABLE=y, and given that the relocation routines run with the
MMU and caches enabled, literal loads of relocated values performed with
the MMU off are not guaranteed to return the latest value unless the
memory covering the literal is cleaned to the PoC explicitly.
So defer the literal load until after the MMU has been enabled, just like
we do for primary_switch() and secondary_switch() in head.S.
