ARM: ts_defconfig: Changes for TS-7553-V2 support

Specifically adds IIO drivers, mono LCD driver, adds SNVS power
key as a builtin for compatibility with `keypad-test` demo in
ts7553v2-utils.git.

The framebuffer console is needed for TPC platforms, it causes
some issues in the TS-7553-V2 that will be resolved later.

Also removes drivers that would never be used, moves a few from
builtin to module, adds some other features/drivers in as a
module for potential future support.
