Subject: [PATCH v2 0/3] Fix reg ranges for main_pktdma dma-controller node

The dma-controller node 'main_pktdma' has few memory regions with
wrong sizes.

DMASS0_PKTDMA_RINGRT is marked as 4MB region when it is actually a 2MB
region. Similarly, DMASS0_PKTDMA_TCHANRT is marked as 256KB region but
the actual size is 128KB as shown in TRM in the section for Main Memory
Map (Table 2-1)

Fix these region across AM62, AM62A and AM62P (which is also used in
J722S)

TRM:

AM625: <https://www.ti.com/lit/pdf/spruiv7>
AM62A7: <https://www.ti.com/lit/pdf/spruj16>
AM62P: <https://www.ti.com/lit/pdf/spruj83>
J722S: <https://www.ti.com/lit/zip/sprujb3>

Changelog v1->v2:
- Add main_pktdma node name in commit message for more clarity about the
  dma-controller and mention the table for memory map in TRM in each patch.
