[PATCH -next] ARM: spear: Fix build error with CONFIG_ARCH_SPEAR3XX

[Chen Lifu <chenlifu@huawei.com>]

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.
