[linux-yocto] [PATCH 2/3] cfg/efi.cfg: built-in CONFIG_EFIVAR_FS to support Intel VROC

[Liwei Song]

The only way to boot from Intel VROC RAID disk is use initramfs with
mdadm installed, mdadm is used to initialize RAID volume and create
md device, During initialization it need read RAID status from efivarfs,
so efivarfs must be ready before mdadm initialize RAID volume

built-in efivarfs to kernel can aviod the timing problem and make mdadm
work well.
