[LEDE-DEV] [PATCH] ramips: add get_port_stats to mt7530 swconfig driver

[p.wassi at gmx.at]

From: P.Wassi <p.wassi at gmx.at>

Add get_port_stats function to mt7530 swconfig driver.
Signed-off-by: P.Wassi <p.wassi at gmx.at>

If one uses "switch" as a trigger for the LEDs, in order to have
the LEDs blinking when there's traffic, swconfig_leds.c needs to
have a get_port_stats function from the swconfig driver.
The function added here is tested on MT7620A, implemented (register
offsets) according to "MT7620 Programming Guide", page 334, 335.
