[PATCH 1/2] net: fec_mpc52xx_phy: Use %pa to format resource_size_t

[Simon Horman]

The correct format string for resource_size_t is %pa which
acts on the address of the variable to be formatted [1].

Introduced by commit 9d9326d3bc0e ("phy: Change mii_bus id field to a string")

Flagged by gcc-14 as:
