spi: pxa2xx: Clear all RFT bits in reset_sccr1() on Intel Quark

commit 152bc19e2fc2b7fce7ffbc2a9cea94b147223702 upstream.

It seems the commit e5262d0568dc ("spi: spi-pxa2xx: SPI support for Intel Quark
X1000") misses one place to be adapted for Intel Quark, i.e. in reset_sccr1().

Clear all RFT bits when call reset_sccr1() on Intel Quark.
