In order to ease the introduction of a new BSEC3 driver for STM32MP25,
the BSEC2 driver is reworked. Unused functions are removed. The
bsec_base global variable is removed in favor of the macro BSEC_BASE.
A rework is also done around function checking the state of BSEC.

Cortex-X3 erratum 2302506 is a cat B erratum that applies to
revisions r0p0-r1p1 and is fixed in r1p2. The workaround is to
set bit[0] of CPUACTLR2 which will force PLDW/PFRM ST to behave
like PLD/PRFM LD and not cause invalidation to other PE caches.
There might be a small performance degradation to this workaround
for certain workloads that share data.

As stated in the commit introducing the NS_TIMER_SWITCH build flag,
saving/restoring this registers causes the non-secure timer to stop
while in the secure world and non-secure timer interrupts are prevented
from asserting until we return to the non-secure world. This breaks
any realtime OS on the non-secure side that uses this timer for
realtime scheduling.
This flag is by default off, but OP-TEE SPD enables it. The K3 OP-TEE
platform makes no use of these registers and we would like to have
support for realtime OSs while also supporting the OP-TEE SPD. Disable
this flag in our platform definition.

Currently there is only 1 state for CPU idle which is used while CPU
power down from Linux CPU idle feature. But CPU power down when firmware
send CPU power down request needs new state in self suspend to
distinguish in firmware for CPU power down from power down request or CPU
power down from Linux CPU idle. So add new state PM_STATE_CPU_OFF to
indicate CPU power down from power down request from firmware.
PM_STATE_CPU_OFF state is supported from self-suspend version 3. So
added feature check which sends new state in case of new firmware and
old state i.e. PM_STATE_CPU_IDLE in case of old firmware.

of issue in GIC configuration. In current Versal NET specific GIC
functions, redistributor configuration is not happening properly.
Because of that SGI interrupt from one processor to another processor

over all GIC redistributor frames and discovers per cpu redistributor
frame. Also, it initializes corresponding interface in GICv3.
