hw: arm: Remove use of tabs in some source files

Some of the source files for older devices use hardcoded tabs
instead of our current coding standard's required spaces.
Fix these in the following files:
	- hw/arm/boot.c
	- hw/char/omap_uart.c
	- hw/gpio/zaurus.c
	- hw/input/tsc2005.c

This commit is mostly whitespace-only changes; it also
adds curly-braces to some 'if' statements.

This addresses part of https://gitlab.com/qemu-project/qemu/-/issues/373
but some other files remain to be handled.
