[PATCH u-boot-marvell] ddr: marvell: axp: fix array types have different bounds warning

The arrays `pbs_dq_mapping`, `div_ratio1to1` and `div_ratio2to1` have
different bounds declared in header files where these variables are also
defined from the ones declared in source files.

This causes the compiler to complain (when building with LTO):
  ddr3_sdram.c:24:12: warning: type of ‘pbs_dq_mapping’ does not match
                               original declaration
			       [-Wlto-type-mismatch]
  ddr3_patterns_64bit.h:911:5: note: array types have different bounds
  ddr3_patterns_64bit.h:911:5: note: ‘pbs_dq_mapping’ was previously
                                     declared here

ddr3_dfs.c:45:11: warning: type of ‘div_ratio1to1’ does not match
                           original declaration [-Wlto-type-mismatch]
ddr3_axp_vars.h:167:4: note: array types have different bounds
ddr3_axp_vars.h:167:4: note: ‘div_ratio1to1’ was previously declared
                             here

ddr3_dfs.c:46:11: warning: type of ‘div_ratio2to1’ does not match
                           original declaration [-Wlto-type-mismatch]
ddr3_axp_vars.h:196:4: note: array types have different bounds
ddr3_axp_vars.h:196:4: note: ‘div_ratio2to1’ was previously declared
                             here

CI managed to trigger this as an error when compiling with LTO for AXP.

Fix this by using values from the header files, which seem to be the
correct ones.
