net: macb: Add null check for PCLK and HCLK
[ Upstream commit cd5afa91f078c0787be0a62b5ef90301c00b0271 ]
Both PCLK and HCLK are "required" clocks according to macb devicetree
documentation. There is a chance that devm_clk_get doesn't return a
negative error but just a NULL clock structure instead. In such a case
the driver proceeds as usual and uses pclk value 0 to calculate MDC
divisor which is incorrect. Hence fix the same in clock initialization.
