Add a eint_bank member to the allwinner_pins structure. On Allwinner SoCs not all pins can do interrupt. Older SoC (A10/A13 and A20) there is a maximum number of interrupts set to 32 and all the configuration is done in the same registers. While on "newer" SoCs (>=A31) interrupts registers are splitted per pin bank (i.e. all interrupts available in bank B will be configured with a sets of registers and the one in bank G in another set). While here set the names to all interrupts function to pX_eintY where X is the bank name and Y the interrupt number. To whom ever in the future look at the H5 manual and notice that the bank F have interrupts support : This isn't true, trust me. MFC after: 1 month
