avb: Make AVB independent of fastboot

AVB only uses CONFIG_FASTBOOT_BUF_ADDR from fastboot for memory.
This memory is used for assigning temporary buffers.
This can be assigned a new variable and used as CONFIG_AVB_BUF_ADDR.
This is to support future boards that support AVB but dont support
USB and therefore dont support FASTBOOT.
