If devm_spi_register_master() fails in meson_spicc_probe(),
spicc->core is left undisabled. The patch fixes that.
Found by Linux Driver Verification project (linuxtesting.org).

Add new compatible string to support SPICC controller which
found at Amlogic Meson-AXG SoC. This is aiming at adding

The SPICC hardware block on the Amlogic SoCs is Communication oriented and
can do Full-Duplex 8- to 32-bit width SPI transfers up to 30MHz.
The current driver only supportd the PIO transfer mode since the DMA seems
broken on available hardware.
