BL31 image has grown with feature addition over time. In particular the
RESET_TO_BL2 + ENABLE_PIE + DEBUG combination of options lead to BL31
image overlap head of BL2 image. In this configuration BL2 is meant to
stay resident as PE reset occurs from BL2. Apply changes similar to [1]
such that BL2 start address is pushed forward and leaves more room for
BL31 end of image.

fix(cadence): update console flush uart driver

The implementation of code changes manages the transmit FIFO (TxFIFO)
in the UART driver. The added code snippet includes a sequence of
instructions that ensures efficient handling of data transmission
and synchronization with the host software.

The code first checks the TxFIFO empty flag to determine whether
there is data available for transmission. If the TxFIFO is not empty,
the code waits until it becomes empty, ensuring that the transmit
operation is synchronized with the availability of data.
Subsequently, the code monitors the transmit operation's activity
status. It waits until the transmit operation becomes inactive,
indicating the completion of the previous transmission.

This synchronization step ensures that new data can be added to the
TxFIFO without causing any loss of transmission time.

Update console_flush() function, the function waits for the
Transmitter FIFO to empty and checks the transmitter's active state.
If the transmitter is in an active state, it means it is currently
shifting out a character.

refactor(cpufeat): introduce wrapper macro for read_feat_...() functions

At the moment we have some elaborate, but very schematic functions to
allow checking for CPU feature enablement. Adding some more becomes
tedious and is also error-prone.

Provide two wrapper macros that reduce most of the features to a
single line:
- CREATE_FEATURE_FUNCS(name, idreg, idfield, guard)
creates two functions read_<name>_id_field() and is_<name>_supported(),
that check the 4-bit CPU ID field starting at bit <idfield> in <idreg>
for being not 0, and compares it against the build time <guard> symbol.
For the usual feature (like PAN) this looks like:
CREATE_FEATURE_FUNCS(feat_pan, id_aa64mmfr1_el1,
ID_AA64MMFR1_EL1_PAN_SHIFT, ENABLE_FEAT_PAN)

- CREATE_FEATURE_FUNCS_VER(name, read_func, idvalue, guard)
creates one function to check for a certain CPU ID field *value*, so
when "!= 0" is not sufficient. It's meant to be used in addition to
the above macro, since that generates the CPU ID field accessor
function:
CREATE_FEATURE_FUNCS(feat_amu, id_aa64pfr0_el1, ID_AA64PFR0_AMU_SHIFT,
ENABLE_FEAT_AMU)
CREATE_FEATURE_FUNCS_VER(feat_amuv1p1, read_feat_amu_id_field,
ID_AA64PFR0_AMU_V1P1, ENABLE_FEAT_AMUv1p1)

Describe the existing feature accessor functions using those new macros,
to reduce the size of the file, improve readability and decrease the
possibility of (copy&paste) bugs.

feat(fvp): spmd logical partition smc handler

This patch adds a basic el3 spmd logical partition to the fvp platform
via a platform specific smc handler. One of the use cases for el3
logical partitions is to have the ability to translate sip calls into
ff-a direct requests via the use of spmd logical partitions. The smc
handler creates a direct request based on the incoming smc parameters
and forwards the call as a direct request from the spmd logical
partition to the target secure partition.
