In lockstep mode, r5 core0 uses TCM of R5 core1. Following is lockstep
mode memory region as per hardware reference manual.
| *TCM* | *R5 View* | *Linux view* |
| R5_0 ATCM (128 KB) | 0x0000_0000 | 0xFFE0_0000 |
| R5_0 BTCM (128 KB) | 0x0002_0000 | 0xFFE2_0000 |
However, driver shouldn't model it as above because R5 core0 TCM and core1
TCM has different power-domains mapped to it.
Hence, TCM address space in lockstep mode should be modeled as 64KB
regions only where each region has its own power-domain as following:
| *TCM* | *R5 View* | *Linux view* |
| R5_0 ATCM0 (64 KB) | 0x0000_0000 | 0xFFE0_0000 |
| R5_0 BTCM0 (64 KB) | 0x0002_0000 | 0xFFE2_0000 |
| R5_0 ATCM1 (64 KB) | 0x0001_0000 | 0xFFE1_0000 |
| R5_0 BTCM1 (64 KB) | 0x0003_0000 | 0xFFE3_0000 |
This fix makes driver maintanance easy and makes design robust for future
platorms as well.

This patch doesn't fix a bug, i.e users won't see any changes once this patch
gets applied. As such there is no need for a "Fixes" tag. When you resend this
patch (see below), please remove the line.
