[SCSI] ufs: fix the setting interrupt aggregation counter
IACTH(Interrupt aggregation counter threshold) value is allowed
up to 0x1F and current setting value is the maximum.
This value is related with NUTRS(max:0x20) of HCI's capability.
Considering HCI controller doesn't support the maximum, IACTH
setting should be adjusted with possible value.
For that, existing 'ufshcd_config_int_aggr' is split into two part
[reset, configure].
