pinctrl: mcp23s08: Rename and change function that wraps regmap_update_bits()

Browse source 
The semantic of mcp_set_mask() was surprising to me when I first read
that driver. So it was unexpected that in the call

	mcp_set_mask(mcp, MCP_OLAT, mask, value);

value was a bool. Make the function a thinner wrapper around
regmap_update_bits() and rename it to also have a similar name.
