MIPS: Alchemy: Stop IRQ name sharing
Eliminate the sharing of IRQ names among the differenct Alchemy
variants. IRQ numbers need no longer be hidden behind a
CONFIG_SOC_AU1XXX symbol: step 1 in my quest to make the Alchemy
code less reliant on a hardcoded subtype.
This patch also renames the GPIO irq number constants. It's really
an interrupt line, NOT a GPIO number!
Code which relied on certain irq numbers to have the same name
across all supported cpu subtypes is changed to determine current
cpu subtype at runtime; in some places this isn't possible so
a "compat" symbol is used.
Run-tested on DB1200.
