[PATCH v1 1/1] spi: pxa2xx: Clear all RFT bits in reset_sccr1() on Intel Quark

[Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx>]

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.

Fixes: e5262d0568dc ("spi: spi-pxa2xx: SPI support for Intel Quark X1000")
