Instead on PA2.0 usage of extru can clobber upper 32-bits. This patch fixes the comment. Signed-off-by: Helge Deller <deller@gmx.de>

It leaves the most-significant 32 bits of the target register in an undefined state. On 64-bit machines, the macro uses depdi to perform safe deposits in the least-significant 32 bits.

Although the snapdragon driver isn't relevant for parisc, it is nevertheless compiled when CONFIG_COMPILE_TEST is defined. Move the COND() define and other PA-RISC mnemonics inside the #ifdef __ASSEMBLY__ part to avoid this conflict.
