soc_caps.h: remove spi cap that is defined to 0
According to the caps rule, for unsupported feature we don't define anything.
Remove the define 0 that violates this rule.
// Peripheral supports DIO, DOUT, QIO, or QOUT
#define SOC_SPI_PERIPH_SUPPORT_MULTILINE_MODE(spi_host) ({(void)spi_host; 1;})
-// Peripheral doesn't support output given level during its "dummy phase"
-#define SOC_SPI_PERIPH_SUPPORT_CONTROL_DUMMY_OUTPUT 0
