spi: cadence-qspi: Remove condition for calling enable linear mode

cadence_qspi_apb_enable_linear_mode() has a weak function defined, so no
need to gaurd this under if (CONFIG_IS_ENABLED(ARCH_VERSAL)).

In cadence_qspi_apb_write_execute(), enable linear mode is called twice by
mistake, remove extra one.
