irqchip/mmp: Remove non-DT codepath
Building with "W=1" warns about missing declarations for
two functions in the mmp irqchip driver:
drivers/irqchip/irq-mmp.c:248:13: error: no previous prototype for 'icu_init_irq'
drivers/irqchip/irq-mmp.c:271:13: error: no previous prototype for 'mmp2_init_icu'
The declarations are present in an unused header, but since there is no
caller, it's best to just remove the functions and the header completely,
making the driver DT-only to match the state of the platform.
