Arm SCMI updates for v7.1

This batch mainly improves SCMI robustness on systems where the SCP does
not generate completion interrupts, and includes two small follow-up
cleanups in the SCMI core.

The main functional change adds support for the new DT property
'arm,no-completion-irq'. When present for mailbox/shared-memory based
SCMI implementations, the driver forces SCMI operations into polling
mode so affected platforms can continue to operate even with broken
firmware interrupt behavior.

In addition, it
 - replaces open-coded size rounding in the base protocol path with
   round_up() for clarity, with no functional change
 - updates the SCMI quirk snippet macro implementation so quirk handlers
  can use break and continue directly when invoked inside loop contexts
