ipl_tools/chreipl: Rename BOOTPARMS_FCP_MAX to BOOTPARMS_SCPDATA_MAX

Browse Source 
chreipl passes additional boot parameters via the firmware scp_data
sysfs attribute. This mechanism is shared by multiple re-IPL types (FCP,
NVMe, and ECKD) and they all have the same scp_data size limit. The
BOOTPARMS_FCP_MAX name is therefore misleading.

Rename BOOTPARMS_FCP_MAX to BOOTPARMS_SCPDATA_MAX and update all callers
to make the intent clear and avoid implying this limit is FCP-only.
