From: Colin Ian King <colin.king@canonical.com>
Don't populate various tables on the stack but make them static const.
Makes the object code smaller by over 280 bytes:
Before:
text data bss dec hex filename
39887 5080 64 45031 afe7 hisi_sas_v2_hw.o
After:
text data bss dec hex filename
39318 5368 64 44750 aece hisi_sas_v2_hw.o
