spi: fsl_qspi: support i.MX6UL/6ULLL/7D

The QSPI module on i.MX7D is modified from i.MX6SX. The module used on
i.MX6UL/6ULL is reused from i.MX7D. They share same tx buffer size.

The endianness is not set at qspi driver initialization. So if we don't
boot from QSPI, we will get wrong endianness when accessing from AHB
address directly.

Add the compatible entry for 6ul/7d.
