bnxt_en: Add context memory initialization infrastructure.
Currently, the driver calls memset() to set all relevant context memory used by the chip to the initial value. This can take many milliseconds with the potentially large number of context pages allocated for the chip. To make this faster, we only need to initialize the "context kind" field of each block of context memory. This patch sets up the infrastructure to do that with the bnxt_mem_init structure. In the next patch, we'll add the logic to obtain the offset of the "context kind" from the firmware. This patch is not changing the current behavior of calling memset() to initialize all relevant context memory.
