hw/display/pxa2xx: Apply brace-related coding style fixes to template…

… header

We're about to move code from the template header into pxa2xx_lcd.c.
Before doing that, make coding style fixes so checkpatch doesn't
complain about the patch which moves the code. This commit fixes
missing braces in the SKIP_PIXEL() macro definition and in if()
statements.
