[linux-yocto][linux-yocto v5.10/standard/sdkv5.10/xlnx-soc][PATCH 13/13] spi: spi-cadence-quadspi: fix linking failure for ARCH arm

[quanyang.wang]

From: Quanyang Wang <quanyang.w...@windriver.com>

64-bit division "(u64 A) / (u32 B)" will break linking on ARCH arm:

arm-linux-gnueabihf-ld: drivers/spi/spi-cadence-quadspi.o: in function 
`cqspi_setdlldelay':
spi-cadence-quadspi.c:(.text+0x1400): undefined reference to `__aeabi_uldivmod'

Fix this by using do_div.
