parisc: Remove BKL from eisa_eeprom

Remove the empty ioctl and the cycle_kernel_lock() in
eisa_eeprom_open() which got there with the big BKL push down. There
is nothing to wait for and sychronize with after the misc device has
been registered.

Remove the empty ioctl as well. The generic code handles the -ENOTTY
if no ioctl function is provided.
