spl: Move all VPL, TPL and PowerPC specific CONFIG options to separate files
- Move all PowerPC (and some shared with Layerscape) options to common/spl/Kconfig.nxp - Move all other TPL related options to common/spl/Kconfig.tpl - Move all VPL related options to common/spl/Kconfig.vpl This makes the whole of common/spl/Kconfig slightly more readable.

a number of settings (essentially name/value pairs) which can

Enable support for GPIOs (General-purpose Input/Output) in VPL.

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 VPL to enable a 'sign-of-life' LED,
|

for example. Enable this option to build the drivers in
