tree/: Change chip restore data type from uint8_t to void ptr

Chip restore callbacks currently are used by
- spi25_statusreg.c unlock functions to restore status register 1.
- s25f.c to restore config register 3.

Both of these cases only need to save a single uint8_t value to restore
the original chip state, however storing a void pointer will allow more
flexible chip restore behaviour. In particular, it will allow
flashrom_wp_cfg objects to be saved and restored, enabling
writeprotect-based unlocking.

BRANCH=none
TEST=Tested on grunt DUT (prog: sb600spi, flash: W25Q128.W):
     `flashrom --wp-range 0x0,0x1000000 \
      flashrom --wp-status     # Result: range=0x0,0x1000000 \
      flashrom -w random.bin   # Result: success \
      flashrom -v random.bin   # Result: success \
      flashrom --wp-status     # Result: range=0x0,0x1000000`
