[ARM] OMAP2/3 clockdomains: add CM and PRM clkdms
Add clockdomains for the CM and PRM. These will ultimately replace the "wkup_clkdm", which appears to not actually exist on the hardware. Signed-off-by: Paul Walmsley <paul@pwsan.com> Signed-off-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
