jtag: bcm2835gpio: fix macro definition

Browse Source 
The macros trigger few errors with checkpatch:

	ERROR:MACRO_ARG_REUSE: Macro argument reuse 'g' - possible
	side-effects?

	ERROR:TRAILING_STATEMENTS: trailing statements should be
	on next line

	ERROR:SPACING: spaces preferred around (several cases)

	ERROR:SINGLE_STATEMENT_DO_WHILE_MACRO: Single statement
	macros should not use a do {} while (0) loop

plus an empty line triggers

	ERROR:BRACES: Blank lines aren't necessary before a close
	brace '}'

Fix them!
