Subject: bnx2x: Remove hw_reset_t function casts
Patch-mainline: v5.5-rc1
Git-commit: 548e5ffe2e11d10c54f8425019900c87788fd838
References: bsc#1154395

All .rw_reset callbacks except bnx2x_84833_hw_reset_phy() use a
void return type. No callers of .hw_reset check a return value and
bnx2x_84833_hw_reset_phy() unconditionally returns 0. Remove all
hw_reset_t casts and fix the return type to void.
