Subject: [PATCH v3] PCI: mt7621: Convert driver into 'bool'

Driver is not ready yet to be compiled as a module since it depends on some
MIPS not exported symbols. 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_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").

Hi Sergio,

I believe this is still to be pulled in some tree, just asking for
confirmation, please let me know and I will queue it.

Thanks,
