ucc_geth ethernet driver is the only driver using immrbar_virt_to_phys() and it
uses it incorrectly.
This patch fixes ucc_geth driver then removes immrbar_virt_to_phys()

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.

While this has its advantages, the capture kernel would initialize all

The CAPI driver creates virtual PHB (vPHB) from the CAPI adapter.
The vPHB's IO and memory windows aren't built from device-tree node
as we do for normal PHBs. A error message is thrown in below path
when trying to probe AFUs contained in the adapter. The error message
is confusing and unnecessary.
This fixes the typo about the _PAGE_PTE in set_pte_at() by changing
"tryint" to "trying to".

Recent versions of OPAL can provide names for the various OPAL interrupts,
so let's use them. This also modernises the code that fetches the
interrupt array to use the helpers provided by the generic code instead
of hand-parsing the property.
