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. Signed-off-by: Manuel Lauss <manuel.lauss@gmail.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
