mhi: core: Add the basic sanity to check the irq registration

Browse Source 
As part of MHI Power On sequence, registering the mhi irq through
request_threaded_irq function. In case of failure in mhi irq
registration, we simply return without printing the error message.
So, added the error message with printing mhi irq number and return
value in failure case of irq registration.
