google/eve: Use rt5514 instead of 4ch DMIC
On this platform the DMICs are connected to the rt5514 DSP instead of directly connected to the SOC. Use the new rt5514 NHLT blob instead of the 4ch DMIC blob and add the required I2C and SPI entries in devicetree so this can get probed properly. BUG=b:35585307 BRANCH=none TEST=build and boot on Eve P1 and check for rt5514 driver enumerated by the kernel Change-Id: I0f2cb532771ee1857df7f33c52a96acf96dc1f54 Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: https://review.coreboot.org/18817 Tested-by: build bot (Jenkins) Reviewed-by: Aaron Durbin <adurbin@chromium.org> Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net> Reviewed-by: Furquan Shaikh <furquan@google.com>
