[PATCH v5 2/2] media: hantro: use DEFINE_RUNTIME_DEV_PM_OPS

[Tharit Tangkijwanichakul <tharitt97@gmail.com>]

The runtime suspend and resume callbacks are currently guarded by
CONFIG_PM. Removing the guard directly would leave the callbacks unused
when CONFIG_PM is disabled.

Define the PM operations with DEFINE_RUNTIME_DEV_PM_OPS() and use
pm_ptr() when assigning them to the platform driver. This keeps the PM
callbacks available when needed while avoiding unused-function warnings
for CONFIG_PM=n builds.
