mtd: flashchip: explicitly include <linux/wait.h>

While reviewing the hyperbus sfdp proposal the following problem was
noticed:

In file included from ./include/linux/mtd/gen_probe.h:10,
                 from drivers/mtd/hyperbus/hyperbus-sfdp.c:6:
./include/linux/mtd/flashchip.h:77:9: error: unknown type name ‘wait_queue_head_t’
   77 |         wait_queue_head_t wq; /* Wait on here when we're waiting for the chip
      |         ^~~~~~~~~~~~~~~~~

It is good practice to directly include all headers used, it avoids
implicit dependencies and spurious breakage if someone rearranges
headers and causes the implicit include to vanish.

Explicitly include <linux/wait.h> in include/linux/mtd/flashchip.
