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
configuration from the FDT data, then set the pins into the requested
state. As part of this the gpio controller now reports the correct number
of pins instead of returning the number of bank * 32.
To allow for a future consolidated kernel we add the SOC_ALLWINNER_A10 and
SOC_ALLWINNER_A20 kernel options. These need to be set as appropriate for
the SoC the kernel will boot on.
