[PATCH] revert fs/char_dev.c CONFIG_BASE_FULL change

This reverts a fs/char_dev.c patch that was merged into BK on March 3.

The problem is that it breaks things ... __register_chrdev_region() has
a block of code, commented "temporary" for over two years now, which
fails rudely during PCMCIA initialization or other register_chrdev()
calls, because it doesn't "degrade to linked list".  This keeps whole
subsystems from working.

A real fix to that "temporary" code should be possible, using some better
scheme to allocate major numbers, but it's not something I want to spend
time on just now.
