[Qemu-devel] [PATCH v2 2/7] target/ppc: introduce single vsrl_offset() function

[Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk>]

Instead of having multiple copies of the offset calculation logic, move it to a
single vsrl_offset() function.

This commit also renames the existing get_vsr()/set_vsr() functions to
get_vsrl()/set_vsrl() which better describes their purpose.
