INAGAKI Hiroshi 3ce3c3e65a ramips: use parser_trx for Buffalo WCR-1166DS 
Buffalo WCR-1166DS uses trx-fomatted firmware and the custom magic
number (0x5C436F74, "\Cot") is required for OpenWrt installation from
OEM WebUI.
But the current mtdsplit_trx doesn't support the custom magic number and
fail to parse and split to kernel and rootfs when the factory image is
flashed. Then, the kernel fails to mount rootfs automatically and panics.

Before the commit fddc78bc11, mtdsplit_trx
was patched in ramips target and the device-specific magic number was
supported only for WCR-1166DS[1].
But the patch was not inherited to the later version of the kernel and
deleted by the above commit, then, the custom magic number support was
broken.

[1]: 05d6e92594/target/linux/ramips/patches-4.4/0400-mtd-mtdsplit-add-support-for-custom-trx-magic-for-Buffalo-WCR-1166DS.patch (L27)

This patch fixes this issue by using parser_trx with specifying custom
magic number in dts instead of mtdsplit_trx.
