[PATCH] skge: function amd macro name change
The inlines and macro's needed some cleanup's and fixes:
* change name of macro SKGEMAC_REG to SK_REG to better reflect usage
and fix comments
* ditto for SK_GEXM_REG -> SK_XMAC_REG and SKGEGMA_REG -> SK_GMA_REG
* change skge_gm_ to just gm_ since it is just a local function and long
names look ugly.
* change skge_xm_ to just xm_
* fix xm_write32 to write as two u16's with correct byte order
* fix xm_outaddr to correctly use offset
