[ARM] Add rtc-cmos driver for ISA-based footbridge platforms
... but the rtc-cmos is rather broken; if PNP is enabled, it assumes that we have ACPI (!) which is quite bogus on these platforms - which may have ISAPNP but not ACPI. Something to be solved in the future. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
