bcm53xx: add Tenda AC9 switch workaround
This fixes regressed support for Tenda AC9 which got broken somewhere
between LEDE 17.01 and OpenWrt 18.06.
At some point bcm47xx_nvram_gpio_pin() started working on bcm53xx
devices and it resulted in swconfig b53 performing GPIO-based switch
reset. It exposed some bug as switch stopped working.
The problem is most likely to be some missing initialization step. Tenda
AC9 comes with BCM53125 rev 4 (pretty common chip) but apparently needs
some extra quirk.
As a workaround (it doesn't make much sense to debug swconfig driver
which has a working DSA replacement) simply avoid full switch reset.
