[PATCH 3/4] soc: xilinx: use a properly named field instead of flags

Instead of defining a flags field and a single bit in this field to
signal that a PM node has been requested, use a boolean field with a
descriptive name.

No functional change, but using a proper name instead of flags makes the
code easier to read.
