mmc: sdhi: Allow named IRQs to use specific handlers

Browse source 
Allow named IRQs to use corresponding specific handlers. If named IRQs are
used, at least an "sdcard" IRQ has to be specified by the platform. If
names are not used, an arbitrary number of IRQs can be provided by the
platform, in which case the generic ISR will be used for each of them.
