Arm SCMI/FF-A fixes for v7.2

Fix two runtime issues in the SCMI framework. Use full 64-bit division
when rounding range-based clock rates, avoiding divisor truncation and
a possible divide-by-zero on 32-bit systems. Rate-limit notification
queue-full warnings emitted from interrupt context to prevent printk
floods and prolonged system stalls during notification bursts. Also
correct a grammar error in the ARM_SCMI_POWER_CONTROL Kconfig help
text.

Fix the FF-A driver RX/TX buffer sizing logic to respect the maximum
buffer size advertised by firmware, while retaining compatibility with
older implementations that may reject PAGE_SIZE-rounded buffers.
Also fix a NULL pointer dereference in ffa_partition_info_get() by
rejecting NULL UUID strings before passing them to uuid_parse().
