When configuring GNU GCC as the C compiler, we usually use the GNU BFD
linker directly to link by default. However, this complicates things
because we also need to support LTO, which can only be done when linking
is done via the C compiler, and we cannot change the linker later on if
some other part of the build system wants to enable LTO.
This change migrates the default choice of linker to GCC if the C
compiler is GCC, in order to enable this use-case. This should have no
impact on anything outside of the build system, as by default GCC merely
acts as a wrapper around BFD.

On the i.MX8M SoCs, TF-A doesn't itself initialize the UART, but depends
on BL2 to set it up beforehand. To allow using the same TF-A binary on
boards with different UART assignment, TF-A On i.MX8M M/N/P supports
dynamically determining the UART in use. The code is also applicable to
the i.MX8MQ, so enable it there too.

Currently both FEAT_MTE and FEAT_MTE_PERM aren't used for enabling
of any feature bits in EL3. So remove both FEAT handling.
All mte regs that are currently context saved/restored are needed
only when FEAT_MTE2 is enabled, so move to usage of FEAT_MTE2 and
remove FEAT_MTE usage.
BREAKING CHANGE: Any platform or downstream code trying to use
SCR_EL3.ATA bit(26) will see failures as this is now moved to be
used only with FEAT_MTE2 with

This patch gives i.MX8ULP's HIFI4 DSP R/W access to the
following additional resources (peripherals):
1) LPUART7
2) IOMUXC1
3) PCC4
4) CGC1
Doing this allows the firmware running on the DSP to
set up serial communication, which also requires doing
pinctrl and clock management-related operations.
Access to the aforementioned resources is given by
configuring the XRDC module.

Erratum 2413290 is a Cat B erratum that is present only
in revision r0p1 and is fixed in r1p1.
The initial implementation did not consider that this
fix is to be applied only when SPE (Statistical Profiling
Extension) is implemented and enabled. This patch applies
the fix by adding a check for ENABLE_SPE_FOR_NS.

Cortex-A720 erratum 2926083 is a Cat B erratum that is present
in revisions r0p0, r0p1 and is fixed in r0p2. The errata is only
present when SPE (Statistical Profiling Extension) is implemented
and enabled.
The workaround is to set bits[58:57] of the CPUACTLR_EL1 to 'b11
when SPE is "implemented and enabled".

In the high system load situation, bus latency increase was observed
and it made impact to other feature (e.g. audio dropouts). This is
because some modules push as much as possible traffic into the DBSC4
CAM for execution, and make increasing bus latency. Re-defining swap
priorities reduce this situation. This advice has been confirmed by
hardware developer.
