Patch Review

Adds the `rzg3e_mipi_dsi_info` hw_info struct and registers the RZ/G3E compatible.

**Issue (const correctness)**: `rzg3e_mipi_dsi_info` is declared as:
```c
static struct rzg2l_mipi_dsi_hw_info rzg3e_mipi_dsi_info = {
```

But both `rzv2h_mipi_dsi_info` and `rzg2l_mipi_dsi_info` are declared `const`:
```c
static const struct rzg2l_mipi_dsi_hw_info rzv2h_mipi_dsi_info = {
static const struct rzg2l_mipi_dsi_hw_info rzg2l_mipi_dsi_info = {
```

The `rzg3e_mipi_dsi_info` should also be `const` for consistency and safety. There's no reason for it to be mutable.

**Observation**: The `rzg3e_plldsis_limits` array uses two different PLL limit structs indexed by `vclk_idx`, while `rzv2h_plldsi_limits` uses a single set (same limits duplicated). This cleanly implements the design described in the commit message.
