ARM: dts: qcom: ipq8064-rb3011: Add Switch LED for each port

Add Switch LED for each port for MikroTik RB3011UiAS-RM.

MikroTik RB3011UiAS-RM is a 10 port device with 2 qca8337 switch chips
connected.

It was discovered that in the hardware design all 3 Switch LED trace of
the related port is connected to the same LED. This was discovered by
setting to 'always on' the related led in the switch regs and noticing
that all 3 LED for the specific port (for example for port 1) cause the
connected LED for port 1 to turn on. As an extra test we tried enabling
2 different LED for the port resulting in the LED turned off only if
every led in the reg was off.

Aside from this funny and strange hardware implementation, the device
itself have one green LED for each port, resulting in 10 green LED one
for each of the 10 supported port.
