net: stmmac: qcom-ethqos: use u32 for rgmii read/write/update
readl() returns a u32, and writel() takes a "u32" for the value. These are used in rgmii_readl()() and rgmii_writel(), but the value and return are "int". As these are 32-bit register values which are not signed, use "u32". These changes do not cause generated code changes. Update rgmii_updatel() to use u32 for mask and val. Changing "mask" to "u32" also does not cause generated code changes. However, changing "val" causes the generated assembly to be re-ordered for aarch64. Update the temporary variables used with the rgmii functions to use u32.
