msm: ipa4: add masked ipa_wigig debug registers values

Wigig registers share info for two ring pointers in some cases.
add new fields that display only the relevant info per channel.
- Upper 16 bits of status ring HWHEAD are used for RX status ring.
Lower bits are used for TX status ring.
- For TX case: Lower 16 bits of the descriptor ring HWHEAD are
used for even ring IDs and Upper bits are used for odd ring IDs.
