avoid using irq_desc in glamo-mci.c

When building the MMC subsystem as modules,
drivers/mfd/glamo/glamo-mci.ko cannot access irq_desc, because it
isn't exported by kernel/irq/handle.c All the functions that
indirectly access irq_desc are inlined, so they cannot be used to
avoid having to resolve irq_desc.

Fortunately, we can solve the problem locally: we don't really need
to access irq_desc anyway. This patch splits glamo_mci_irq into a
small wrapper that implements the IRQ handler interface and the main
code that doesn't need to know about the semantics of the latter.
Then we simply call the main code with the information we already
have.
