[PATCH net v3 6/6] net: stmmac: squelch sparse warning with casts

[Vince Bridgers <vbridgers2013@gmail.com>]

Add casts to squelch the following sparse warnings so we can see
the ones that matter when they occur.

stmmac_platform.c:260:20: warning: incorrect type in argument 1
			  (different address spaces)
stmmac_platform.c:260:20:    expected void const *static extern
			  [signed] [long] [typedef] [tls] inline [safe] ptr
stmmac_platform.c:260:20:    got void [noderef] <asn:2>*[assigned] addr
stmmac_platform.c:261:32: warning: incorrect type in argument 1
			  (different address spaces)
stmmac_platform.c:261:32:    expected void const *static extern
			  [signed] [long] [typedef] [tls] inline [safe] ptr
stmmac_platform.c:261:32:    got void [noderef] <asn:2>*[assigned] addr
