We need to configure CPU PCIE root port related gpios in early
boot block stage for CPU root ports to work. Since we're removing
this programming from FSP, coreboot needs to take care of programming
this GPIOs. Also we need to enable virtual wire messaging for native
gpios for CPU PCIE root ports.

UART pad configuration should not be done in common code, because that
may cause short circuits, when the user sets a wrong UART index. Thus,
add the corresponding pads to the early UART gpio table for the board as
a first step. Common UART pad config code then gets dropped in CB:48829.
Also switch to `bootblock_mainboard_early_init` to configure the pads in
early bootblock before console initialization, to make the console work
as early as possible. The board does not do any other gpio configuration
in bootblock, so this should not influence behaviour in a negative way
(e.g. breaking overrides).

List of changes:
1. Use devicetree.cb from default location
2. Create variant directory for ADL RVP with external EC as
'adlrvp_p_ext_ec'
3. Add initial overridetree.cb for 'adlrvp_p' and 'adlrvp_p_ext_ec'
to override 'devicetree.cb' as applicable.
4. Move all common files between 'adlrvp_p' and 'adlrvp_p_ext_ec'
to mainboard directory
TEST=Build and boot both ADLRVP with onboard and external EC.
