This new version adds support for early NCR chips.

53C810 non 'A', 53C815 and 53C825 non 'A' are now
attached by the driver (by default).
The driver uses a different SCRIPTS set based on
MEMORY MOVE instructions for these chips.

2 SCRIPTS sets (firmwares) numbered #1 and #2 are
used for the whole support of the 53C8XX family
to get possible:

- FW #1 : Only based on MEMORY MOVE instructions.
          Selected for 810, 815, 825.
- FW #2 : LOAD/STORE based. This is the firmware
          also used by previous driver versions.
          Selected for other chips.

When both `ncr' and `sym' are configured, `sym'
will now attach all the 53C8XX devices by default.
Previous balancing between `ncr' and `sym' can be
preserved by:

- Either editing sym_conf.h and commenting the
  following compile option:
     #define SYM_CONF_GENERIC_SUPPORT
  (This also saves about 3.5Kb of kernel memory).

- Or setting kernel config option
    SYM_SETUP_LP_PROBE_MAP to 64 (bit 0x40)
