ltc: ctr: fix counter increment when LTC_FAST is defined

In CTR mode the counter needs to be incremented upon completion of each
block. Unfortunately, if there is no crypto acceleration
(accel_ctr_encrypt == NULL) and if LTC_FAST is defined, this does not
happen. Add the missing call to fix the issue.

core: fix potential crash when setting transfer entry size

Fix a potential crash when the rounded up end-of-entry exceeds the
boundary of the old end-of-transfer-list when setting the size of
a transfer entry.

The crash happens when the specified entry is the last one in the
transfer list and its rounded up end 'old_ev' exceeds the
'tl_old_ev' which is not rounded up, leading to a negative value
with (tl_old_ev - old_ev).

Logically, 'tl_old_ev > old_ev' is the only case that indicates
there are subsequent entries to be moved.

compatibility with platform already supported in upstream Linux/U-Boot
components, as defined by st,stm32mp15-i2c-non-secure specific

STATS_NB_POOLS is intentionally not incremented since it is
expected to give the number of pools which IDs start from 1

Ensure the stats are all 0 for when RPMB_FS is not supported or we
failed to get the stats info. For this, let's zero initialize the
shared buffer so that these default stats also apply on other stats
that may not be reachable (deprecate public DDR pool, Nexus heap).
