[U-Boot] [PATCH v3 05/13] fastboot: Correct dependencies in FASTBOOT_FLASH

Ensure that when selecting FASTBOOT_FLASH you end up with a buildable
configuration. Prior to this you could select NAND without MTDPARTS
and end up with an image which (surprisingly) excluded NAND.

Also fix dependencies on FASTBOOT_GPT_NAME/FASTBOOT_MBR_NAME which require
you have EFI_PARTITION/DOS_PARTITION enabled.

Changes in v3:
- guard FASTBOOT_GPT_NAME/FASTBOOT_MBR_NAME with EFI/DOS_PARTITION

Changes in v2: None
