MCT driver define an enum which list global and local timer's
irq index. Most of them are not used but MCT_G0_IRQ and
MCT_L0_IRQ and these two are at a fixed offset/index.
Get rid of this enum and use a #define for the used irq index.
While at it, bump-up maximum number of MCT IRQ to match the
binding documentation. And also change the name variable to be
more generic.
No functional changes expected.
