kahlee/ec.c: Use new wide IO function

In preparation to deleting early_setup,c, change early_ec_init() to use new
southbridge.c function sb_set_wideio_range and remove <#ifdef __PRE_RAM__>.

TEST=Build, boot and check serial output, search for "Covered by wideIO xx",
which should match earlier message "Range assigned to wide IO xx" generated
within modified early_ec_init().
