staging: wilc1000: remove wilc memory allocation config

Browse source 
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.

---help---
This choice supports static allocation of the memory
for the receive buffer. The driver will allocate the RX buffer
during initial time. The driver will also free the buffer
by calling network device stop.

bool "Dynamically allocate memory in real time"

This choice supports dynamic allocation of the memory
for the receive buffer. The driver will allocate the RX buffer
when it is required.
