ARM: keystone2: Use macro for DSP GEM power domain
Define a macro for the DSP GEM power domain id number and use it instead of a hard-coded number in the code that disables all the DSPs on various Keystone2 SoCs. Signed-off-by: Suman Anna <s-anna@ti.com> Signed-off-by: Nishanth Menon <nm@ti.com> Reviewed-by: Tom Rini <trini@konsulko.com>
