fix(el3-runtime): leverage generic interrupt controller helpers

Rather than validating the type of interrupts supported by the
platform interrupt controller, the interrupt management framework can
directly use helper utilities implemented by the generic interrupt
controller driver.

fix: make TF-A use provided OpenSSL binary

Currently Tf-A uses whatever openssl binary is on the system to sign
images. However if OPENSSL_DIR is specified in the build flags this can
lead to linking issues as the system binary can end up being linked
against shared libraries provided in OPENSSL_DIR/lib if both binaries
(the system's and the on in OPENSSL_DIR/bin) are the same version.
This patch ensures that the binary used is always the one given by
OPENSSL_DIR to avoid those link issues.

for 'QEMU' and 'RPI3' platforms.

rot_key.pem] Error 2

Issue seems to be occurred when 'ROT key' is generated before creating
the platform build folder(for e.g.build/qemu/debug).

Changes are made to fix this issue by adding orderly dependancy of
the platform folder for the 'ROT key' creation which ensures that
platform folder is created before generating 'ROT key'.

The plat_helpers.S file was almost identical between its RPi3 and RPi4

This adds a plat_rpi_get_model() function, which can be used to trigger
RPi4 specific action, detected at runtime. We use that to do the RPi4
specific L2 cache initialisation.

rpi3: build: Include GPIO driver in all BL stages

So far the Raspberry Pi 3 build needs the GPIO driver just for BL2.
Upcoming changes will require some GPIO code in BL1 and BL31 also, so
move those driver files into the common source section.

This does not affect BL31 code size at all, and bl1.bin just increases
by 144 bytes, but doesn't affect the padded binary size at all.

rpi: Allow using PL011 UART for RPi3/RPi4

The Broadcom 283x SoCs feature multiple UARTs: the mostly used
"Mini-UART", which is an 8250 compatible IP, and at least one PL011.
While the 8250 is usually used for serial console purposes, it suffers
from a design flaw, where its clock depends on the VPU clock, which can
change at runtime. This will reliably mess up the baud rate.
To avoid this problem, people might choose to use the PL011 UART for
the serial console, which is pin-mux'ed to the very same GPIO pins.
This can be done by adding "miniuart-bt" to the "dtoverlay=" line in
config.txt.

To prepare for this situation, use the newly gained freedom of sharing
one console_t pointer across different UART drivers, to introduce the
option of choosing the PL011 for the console.

This is for now hard-coded to choose the Mini-UART by default.
A follow-up patch will introduce automatic detection.
