spl: Support hash, input, pch, pci, rtc, tpm in SPL

Browse Source 
At present these subsystems are only supported in U-Boot proper but it is
sometimes necessary to support them in SPL, or even TPL. Update the
Kconfig and Makefile to support this. Also adjust GPIO so that it can be
used in TPL if required.

config TPL_GPIO_SUPPORT
bool "Support GPIO in TPL"
help
Enable support for GPIOs (General-purpose Input/Output) in TPL.
GPIOs allow U-Boot to read the state of an input line (high or
low) and set the state of an output line. This can be used to
drive LEDs, control power to various system parts and read user
input. GPIOs can be useful in TPL to enable a 'sign-of-life' LED,
for example. Enable this option to build the drivers in
drivers/gpio as part of an TPL build.

Enable support for PCI in TPL. For platforms that need PCI to boot,
