donghui.wang b5531bdf87 ldim: optimize spi interface [1/1] ...

PD#SWPL-183850

Problem:
1,low probability crash when dirspi_dma_trig called in isr
2,async need use coherent buf
3,low probability send unexpected data when start dma trig

Solution:
1,spicc add controller capability
2,async use coherent buf
3,rm dq2/dq3 for t3x ref board
4,optimize dma trig state management
5,alloc descriptor in controller probe but not in dirspi_dma_trig
6,fix clk div 0 error caused by CFG_BUS clearing by dirspi_dma_trig
7, optimize controller isr
8, add spin lock for smp

Verify:
t3x/t5m
