drivers: caam: Fix alignment fault caused by caam_desc_pop()

Size of each JR Output ring entry is of 12 bytes for CAAM
using address pointer size as 64 bit. The descriptor address
pointer thus lies at 32 bit boundary in second output ring entry.
64 bit access of descriptor pointer at 32 bit boundary generates
alignment fault. To fix this, descriptor address pointer should
be accessed as two 32 bit operations.

core: boot: relax init sections from DT related resources

Move the initialization sequences that deal with device tree parsing
support out of the text_init and rodata_init sections to relax memory
pressure on them. To do so this change splits init_primary_helper()
in 2 helper functions: generic_init_primary() for resources expected
in the init sections and paged_init_primary() for resources that move
the pageable sections.

Updates inline comments to state generic_boot_init_primary() lies in
the init area, not in the unpaged area as wrongly stated prior this
change.

core: rename KEEP_INIT() and KEEP_PAGER()

The KEEP_INIT() and KEEP_PAGER() macros are quite often used in C files
immediately after the definition of a function or a structure without a
blank line in between. This style mimics what the Linux kernel does for
a similar use cases: EXPORT_SYMBOL().

Unfortunately, the checkpatch.pl tool expects a blank line after
structure and function definitions, except for a few special cases such
as EXPORT_SYMBOL(). As a result we often get unwanted warnings when we
use KEEP_INIT() and KEEP_PAGER(). Among the exceptions are all words
starting with DECLARE_ or DEFINE_, so by renaming our macros we could
avoid the checkpatch warnings.

This commit renames KEEP_INIT() and KEEP_PAGER() to DECLARE_KEEP_INIT()
and DECLARE_KEEP_PAGER(), respectively. The assembler macros are also
renamed for consistency. No functional change is expected.
