[PATCH] accel/ivpu: Refactor priority_bands_show for readability

[Karol Wachowski <karol.wachowski@linux.intel.com>]

From: Jacek Lawrynowicz <jacek.lawrynowicz@linux.intel.com>

Reduce code duplication and improve the overall readability of the debugfs
output for job scheduling priority bands.

Additionally fix clang-tidy warning about missing default case in the
switch statement.
