Add missing compatible strings from 4.9/960-add-rasbperrypi-compatible.patch, using upstream names for compute modules. Add extra patch to enable the LEDs on lan78xx.

Subject: [PATCH 229/454] ASoC: pcm512x: implement set_tdm_slot interface
PCM512x can accept data padded with additional BCLK cycles
but the driver currently lacks an interface to configure this.
This leads to the problem that S24_LE format in master mode
can result in non-integer clock divisors and pcm512x running
at a rather off rate.
For example 48kHz with 48fs BCLK and SCLK at 24.576MHz uses
a divisor of 10 (rounded down from 10.6666) and results in a
51.2kHz LRCLK. With 64fs BCLK a divisor of 8 is used and
LRCLK runs at exactly 48kHz.
Fix this by providing a minimal set_tdm_slot implementation
so machine drivers can optionally configure custom BCLK ratios.
