bnx2x: Provide declaration of dmae_reg_go_c in header

Provide declaration of dmae_reg_go_c in header.
This symbol is defined in bnx2x_main.c.
And used in that file and bnx2x_stats.c.

However, Sparse complains that there is no declaration
of the symbol in dmae_reg_go_c nor is the symbol static.

 .../bnx2x_main.c:291:11: warning: symbol 'dmae_reg_go_c' was not declared. Should it be static?

Address this by moving the declaration from bnx2x_stats.c to bnx2x_reg.h.

No functional change intended.
Compile tested only.
