2022-12-12mb/google/geralt: Put MIPI panel data in panel_geralt.cBo-Chen Chen
There are eDP and MIPI panels supported in geralt. We put the panels' specified functions - `power_on()` and `configure_panel_backlight()` in panel_geralt.c. Also provide the common interface `get_active_panel()` in panel.c to generalize the display initialization. Since each board may support a different set of MIPI panels, we put the MIPI data in a separate file panel_geralt.c.

2022-12-09mem_chip_info: Update to new formatJulius Werner
The original version of the mem_chip_info structure does not record rank information and does not allow precise modeling of certain DDR configurations, so it falls short on its purpose to compile all available memory information. This patch updates the format to a new layout that remedies these issues. Since the structure was introduced so recently that no firmware using it has been finalized and shipped yet, we should be able to get away with this without accounting for backwards compatibility.

This reverts commit a8172c329fe309f3b5b409c1a59a227186400dd4. In the aforementioned patch, we allowed MCUPM to access secure registers and set the domain to DOMAIN_2. Additional attribute settings are also required when a hardware is set to a specific domain. Otherwise, there would be violation between hardware. Since MT8188 is in bring-up stage, we simply enable access register permission for the DOMAIN_0 by default. So remove the wrong setting for MCUPM, SCP and SSPM. We will complete DEVAPC setting when the settings are confirmed.
