spi: pxa2xx: Fix regression when toggling chip select on LPSS devices

The commit 78b435c9044a ("spi: pxa2xx: Introduce __lpss_ssp_update_priv()
helper") broke speaker output on my ASUS UX5304MA laptop. The problem is
in inverted value that got written in the private register.

Simple bug, simple fix.
