From: Karthik Poosa <karthik.poosa@xxxxxxxxx>
[ Upstream commit 59d237c8a241168c7ae34c48244059b7bafaff38 ]
WRITE_I1 sub-command of the POWER_SETUP pcode command accepts a u16
parameter instead of u32. This change prevents potential illegal
sub-command errors.
v2: Mask uval instead of changing the prototype. (Badal)
v3: Rephrase commit message. (Badal)
