fsl_pq_mdio: Fix kernel oops during OF address translation
Old P1020RDB device trees were not specifing tbipa address for
MDIO nodes, which is now causing this kernel oops:
...
eth2: TX BD ring size for Q[6]: 256
eth2: TX BD ring size for Q[7]: 256
Unable to handle kernel paging request for data at address 0x00000000
Faulting instruction address: 0xc0015504
Oops: Kernel access of bad area, sig: 11 [#1]
...
NIP [c0015504] memcpy+0x3c/0x9c
LR [c000a9f8] __of_translate_address+0xfc/0x21c
Call Trace:
[df839e00] [c000a94c] __of_translate_address+0x50/0x21c (unreliable)
[df839e50] [c01a33e8] get_gfar_tbipa+0xb0/0xe0
...
The old device trees are buggy, though having a dead ethernet is
better than a dead kernel, so fix the issue by using of_iomap().
Also, a somewhat similar issue exist in the probe() routine, though
there the oops is only a possibility. Nonetheless, fix it too.
