Kconfigs: Various: Fix some SPL, TPL and ARM64 dependencies

Several options are presenting themselves on a various boards
where the options are clearly not used.  (ie, arm64 options on
arm9, or SPL/TPL options when SPL or TPL are not defined)

This patch is not attempting to be a complete list of items, but
more like low hanging fruit.

This patch attempts to reduce some of the menuconfig noise
by defining dependencies so they don't appear when not used.
