soc/amd/common/psp_verstage: Make SPI ROM mapping configurable
Earlier entire SPI ROM was mapped to memory. With limited TLB resources in PSP, this approach hit the limit on systems using 32 MiB SPI ROM. Therefore regions in SPI ROM were mapped on need basis. This works well on Picasso, Mendocino and Phoenix SoCs. But unfortunately this causes boot hangs in Cezanne SoC. Add a configuration to map the entire SPI ROM and enable it in Cezanne SoC. For other SoCs, keep the configuration disabled so that only the required SPI ROM region is mapped. BUG=b:309690716 TEST=Build and boot to OS in both Dewatt and Skyrim.
