FROMLIST: char: misc: increase DYNAMIC_MINORS value

DYNAMIC_MINORS value has been set to 64.
Due to this reason, we are facing a module loading fail problem of
device driver like below.

 [   45.712771] pdic_misc_init - return error : -16

We need to increase this value for registering more misc devices.
