[PATCH v2 0/2] drm/xe/pcode: Increase default mailbox timeout

[Karthik Poosa <karthik.poosa@intel.com>]

This small series raises the default pcode mailbox timeout from 1ms to
10ms and consolidates the value behind a single shared macro.

We have observed sporadic mailbox write timeouts where 1ms was not enough
for the command to complete, resulting in spurious -ETIMEDOUT failures.
Bumping the default to 10ms avoids these while staying well within the
pcode mailbox specification guidance.

Patch 1 introduces PCODE_DEFAULT_TIMEOUT_MS and switches the default
pcode read/write paths to it.

Patch 2 drops the duplicate PL_WRITE_MBX_TIMEOUT_MS macro in hwmon and
reuses PCODE_DEFAULT_TIMEOUT_MS, keeping the power limit write in sync
with the pcode default.

This series continues the effort to address the review feedback received
on patch series https://patchwork.freedesktop.org/series/171303/.
