[PATCH 5.10.y-cip 37/61] ravb: remove APSR_DM


Lad Prabhakar
 

From: Sergey Shtylyov <s.shtylyov@...>

commit f4d680e5024805d52a3bbcee20581ab7b83bcfbf upstream.

According to the R-Car Series, 3rd Generation User's Manual: Hardware,
Rev. 1.50, there's no APSR.DM field, instead there are 2 independent
RX/TX clock internal delay bits. Follow the suit: remove #define APSR_DM
and rename #define's APSR_DM_{R|T}DM to APSR_{R|T}DM.

While at it, do several more things to the declaration of *enum* APSR_BIT:
- remove superfluous indentation;
- annotate APSR_MEMS as undocumented;
- annotate APSR as R-Car Gen3 only.
