[PATCH] x86: spl: Add support for NVMe boot device

[Naresh Solanki]

This change adds `BOOT_DEVICE_NVME` to the `enum` list in
`arch/x86/include/asm/spl.h`,
enabling NVMe as a recognized boot device for SPL (Secondary Program
Loader).

Tested x86 hardware with Coreboot + uboot payload.
Verified successful boot to NVMe drive.
