net: stmmac: qcom-ethqos: add rgmii set/clear functions

The driver has a lot of bit manipulation of the RGMII registers. Add
a pair of helpers to set bits and clear bits, converting the various
calls to rgmii_updatel() as appropriate.

Most of the change was done via this sed script:

/rgmii_updatel/ {
	N
	/,$/N
	/mask, / ! {
		s|rgmii_updatel\(([^,]*,\s+([^,]*),\s+)\2,\s+|rgmii_setmask(\1|
		s|rgmii_updatel\(([^,]*,\s+([^,]*),\s+)0,\s+|rgmii_clrmask(\1|
		s|^\s+$||
	}
}

and then formatting tweaked where necessary.
