bus: mhi: core: Improve mhi_sync_power_up handling for SYS_ERR state

Browse source

[ Upstream commit aa1a0e93ed ]

Allow mhi_sync_power_up to handle SYS_ERR during power-up, reboot,
or recovery. This is to avoid premature exit when MHI_PM_IN_ERROR_STATE is
observed during above mentioned system states.

To achieve this, treat SYS_ERR as a valid state and let its handler process
the error and queue the next transition to Mission Mode instead of aborting
early.
