scsi: megaraid: make some symbols static in megaraid_sas_fp.c

Fix the following sparse warning:

drivers/scsi/megaraid/megaraid_sas_fp.c:88:5: warning: symbol
'mega_div64_32' was not declared. Should it be static?
drivers/scsi/megaraid/megaraid_sas_fp.c:370:5: warning: symbol
'MR_GetSpanBlock' was not declared. Should it be static?
drivers/scsi/megaraid/megaraid_sas_fp.c:420:5: warning: symbol
'mr_spanset_get_span_block' was not declared. Should it be static?
drivers/scsi/megaraid/megaraid_sas_fp.c:645:4: warning: symbol 'get_arm'
was not declared. Should it be static?
drivers/scsi/megaraid/megaraid_sas_fp.c:788:4: warning: symbol
'MR_GetPhyParams' was not declared. Should it be static?
drivers/scsi/megaraid/megaraid_sas_fp.c:1345:4: warning: symbol
'megasas_get_best_arm_pd' was not declared. Should it be static?
