spi: sun6i: add quirk for dual and quad SPI modes support

New Allwinner's SPI controllers can support dual and quad SPI modes.
To enable one of these modes, we should set the corresponding bit in
the SUN6I_BURST_CTL_CNT_REG register. DRM (28 bits) for dual mode and
Quad_EN (29 bits) for quad transmission.
