staging: wilc1000: remove wilc memory allocation config

This patch remove memory allocation options in Kconfig. It was used a long time
ago to aquire memory, which we will not use this config anymore.
Remove it's config, related define and codes as well. We will take
PREALLOCATE_AT_LOADING_DRIVER as it is default.
