Subject: ipq40xx: increase SPI frequency for Zyxel NBG6617
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=88f39b72da6ceb5f2f87692369dc41e9c9cced12;p=openwrt%2Fstaging%2Fnbd.git

ipq40xx: increase SPI frequency for Zyxel NBG6617

The mx25l25635f supports clock speed up to 50Mhz.

Also remove obsolete "mx25l25635f" hack and rename
the matching device-tree flash node.

[mention node rename as well. chip is very very likely
always the "f" revision for all NBG6617]
