dts: introduce macro's to help with changing unit-addr
Since there are times that we include a base .dtsi file and change the
reg address we tend to end up with warnings that the reg address and
unit-address don't match. To handle this introduce a simple DT_ADDR(x)
macro that will prepend '0x' to a 'unit-address' style address.
#define DCCM_ADDR 80000000 /* in unit-address format */
dccm0: dccm@DCCM_ADDR {
reg = <DT_ADDR(DCCM_ADDR) 0x1>;
...
};
This allows the dts file to override the value of DCCM_ADDR and than to
have the unit-address of the node and the reg address match.
