commit 77f983a9df42 ("spi: pl022: Use GPIOs looked up by the core")
deleted 'struct pl022_ssp_controller' member 'num_chipselect'.
We get build error when CONFIG_ARCH_SPEAR3XX is set:
arch/arm/mach-spear/spear3xx.c:42:3: error: 'struct pl022_ssp_controller' has no member named 'num_chipselect'
42 | .num_chipselect = 2,
| ^~~~~~~~~~~~~~
arch/arm/mach-spear/spear3xx.c:42:20: warning: initialization of 'void *' from 'int' makes pointer from integer without a cast [-Wint-conversion]
42 | .num_chipselect = 2,
| ^
Fix the issue by deleting the initialization of 'num_chipselect'
in spear3xx.c.

A patch is already applied by Mark to fix this issue.
