This adds separate kconfig options for drivers/sysreset and
drivers/firmware.
Up to now, CONFIG_SPL_DRIVERS_MISC_SUPPORT added drivers/misc to SPL
build but also added drivers/firmware and drivers/sysreset at the same
time.
Since that is confusing, this patch uses CONFIG_SPL_SYSRESET for
drivers/sysreset and adds CONFIG_SPL_FIRMWARE for
drivers/firmware (and accordingly for the TPL options).
CONFIG_SPL_DRIVERS_MISC_SUPPORT stays for including drivers/misc into
the SPL build (and accordingly for TPL) since there are boards using
non-DM (non UCLASS_MISC) files from drivers/misc. Such boards don't
have CONFIG_SPL_MISC enabled, so cannot use this to include
drivers/misc into the SPL build.

There is no prompt string for FIRMWARE config. Without this,
FIRMWARE config cannot be enabled through menuconfing or
config file. Fix this by adding prompt summary.

Texas Instrument's System Control Interface (TI SCI) message protocol is
used in Texas Instrument's System on Chip (SoC) such as those in the K3
family AM654 SoC to communicate between various compute processors with
a central system controller entity.
The TI SCI message protocol provides support for management of various
hardware entities within the SoC. Add support driver to allow
communication with system controller entity within the SoC using the
mailbox client.
This is mostly derived from the TI SCI driver in Linux located at
drivers/firmware/ti_sci.c.

If the system is running PSCI firmware, the System Reset function
(func ID: 0x80000009) is supposed to be handled by PSCI, that is,
the SoC/board specific reset implementation should be moved to PSCI.
U-Boot should call the PSCI service according to the arm-smccc
manner.
The arm-smccc is supported on ARMv7 or later. Especially, ARMv8
generation SoCs are likely to run ARM Trusted Firmware BL31. In
this case, U-Boot is a non-secure world boot loader, so it should
not be able to reset the system directly.
