HV: config: adapt to the generated config.h

This patch drops "#include <bsp_cfg.h>" and include the generated config.h in
CFLAGS for the configuration data.

Also make sure that all configuration data have the 'CONFIG_' prefix.

v4 -> v5:

    * No changes.

v3 -> v4:

    * Add '-include config.h' to hypervisor/bsp/uefi/efi/Makefile.
    * Update comments mentioning bsp_cfg.h.

v2 -> v3:

    * Include config.h on the command line instead of in any header or source to
      avoid including config.h multiple times.
    * Add config.h as an additional dependency for source compilation.

v1 -> v2:

    * No changes.
