Subject: [PATCH 1/2] net: ethernet: ucc_geth: fix MEM_PART_MURAM mode

Since commit 5093bb965a163 ("powerpc/QE: switch to the cpm_muram
implementation"), muram area is not part of immrbar mapping anymore
so immrbar_virt_to_phys() is not usable anymore.

Fixes: 5093bb965a163 ("powerpc/QE: switch to the cpm_muram implementation)
Signed-off-by: Christophe Leroy <christophe.leroy@....fr>
