wifi: iwlwifi: add support for new ini region types

YoYo introduces 2 new region types: prph mac and phy blocks.
The data in this regions consists of a list of
(base address, size) pairs.
This way we can set a block of consecutive registers by the
base address and the size, instead of a list of registers.
Add support for parsing and dumping these new region types
