The following commit added the support for the lostcontext_mask
along with the usage of the flag for l4_abe.

ARM: OMAP4: hwmod data: add support for lostcontext_mask
Unfortunately, the l4_abe does not contain this memory and thus
cannot contain that flag.
Remove the flag from the l4_abe hwmod.
Change as well the mask for omap44xx_aess_hwmod to avoid missing
the status in case LOSTMEM_AESSMEM is set. The AESS logic does
not support retention and thus only the memory state is useful.
It is even mandatory to avoid a crash in the case of the AESS
resume.
TBD: Ideally each hwmod should contain an extra entry for memory
context attached to it. The AESS does contain only one, but some
IP like the IVAHD does have three memories with dedicated status.
The granularity is never used, but at least one global information
for all the memory banks is useful.
