cpu: microblaze: Fix unmet direct dependencies for XILINX_MICROBLAZE0_PVR

As exposed by "make randconfig", CPU_MICROBLAZE uses select to
force-enable XILINX_MICROBLAZE0_PVR, but that symbol depends on
TARGET_MICROBLAZE_GENERIC. The select bypasses this dependency chain,
triggering a Kconfig warning:

  WARNING: unmet direct dependencies detected for XILINX_MICROBLAZE0_PVR
    Depends on [n]: MICROBLAZE [=y] && TARGET_MICROBLAZE_GENERIC [=n]
    Selected by [y]:
    - CPU_MICROBLAZE [=y] && CPU [=y] && MICROBLAZE [=y]

Change XILINX_MICROBLAZE0_PVR from select to depends on, so that the
CPU driver is only available when PVR support has been explicitly
enabled.
