configs/config.protectli_vp2420_no_emmc: create viariant with disabled emmc

Adds ENABLE_EMMC option (default y) to support VP2420e — a hardware
variant without eMMC. SMBIOS product name gets an "e" suffix when the
option is disabled.

`ScsEmmcEnabled` is set by `soc_silicon_init_params()` via
`is_devfn_enabled(PCH_DEVFN_EMMC)` before `mainboard_silicon_init_params()`
is called, so overriding it directly in FSP UPD at the end of
`mainboard_silicon_init_params()` is sufficient.

`pcidev_path_on_root(PCH_DEVFN_EMMC)->enabled` is also cleared to
prevent the device from appearing in ACPI tables.
