Loongson: add a new option FUJITSU_QUIRKS
This option enables the quirks of fujitsu disk on some old FuLoong-2F
series(6002, 6003), If you want to use the libata, this option must be enabled,
otherwise, the kernel will report "IRQ #14 nobody cared". but for the old IDE
driver, this option is not needed and for some new FuLoong-2F series(6004,
6005, 6014, 6015), this must be disabled to avoid the kernel hang on booting.
Note: a better method is determining it through the machtype, but
currently, the machtype only reflect the fuloong, yeeloong, not reflect
the model of them, for example, fuloong-6002, fuloong-6003, in the
future, this machtype should be improved.
