scsi: ufs: core: Fix RPMB link error by reversing Kconfig dependencies

When CONFIG_SCSI_UFSHCD=y and CONFIG_RPMB=m, the kernel fails to link
with undefined references to ufs_rpmb_probe() and ufs_rpmb_remove():

  ld: drivers/ufs/core/ufshcd.c:8950: undefined reference to `ufs_rpmb_probe'
  ld: drivers/ufs/core/ufshcd.c:10505: undefined reference to `ufs_rpmb_remove'

The issue is that RPMB depends on its consumers (MMC, UFS) in Kconfig,
which is backwards. This prevents proper module dependency handling when
the library is modular but consumers are built-in.

Fix by reversing the dependency:

 - Remove 'depends on MMC || SCSI_UFSHCD' from RPMB Kconfig

 - Add 'depends on RPMB || !RPMB' to SCSI_UFSHCD Kconfig

This allows RPMB to be an independent library while ensuring correct
linking in all module/built-in combinations.
