#     PCI: mt7621: Convert driver into 'bool'
#     
#     The driver is not ready yet to be compiled as a module since it depends
#     on some symbols not exported on MIPS.  We have the following current
#     problems:
#     
#       Building mips:allmodconfig ... failed
#       --------------
#       Error log:
#       ERROR: modpost: missing MODULE_LICENSE() in drivers/pci/controller/pcie-mt7621.o
#       ERROR: modpost: "mips_cm_unlock_other" [drivers/pci/controller/pcie-mt7621.ko] undefined!
#       ERROR: modpost: "mips_cpc_base" [drivers/pci/controller/pcie-mt7621.ko] undefined!
#       ERROR: modpost: "mips_cm_lock_other" [drivers/pci/controller/pcie-mt7621.ko] undefined!
#       ERROR: modpost: "mips_cm_is64" [drivers/pci/controller/pcie-mt7621.ko] undefined!
#       ERROR: modpost: "mips_gcr_base" [drivers/pci/controller/pcie-mt7621.ko] undefined!
#     
#     Temporarily move from 'tristate' to 'bool' until a better solution is
#     ready.
#     
#     Also RALINK is redundant because SOC_MT7621 already depends on it.
#     Hence, simplify condition.
#     
#     Fixes: 2bdd5238e756 ("PCI: mt7621: Add MediaTek MT7621 PCIe host controller driver").
