platform: sifive/fu540: Remove FU540_ENABLED_HART_MASK option

Browse Source 
The FU540_ENABLED_HART_MASK compile time option was added for initial
bring-up on SiFive Unleashed. This option is redundant now because
disabled_hart_mask is already removed. Based on this rationale, we
remove FU540_ENABLED_HART_MASK compile time option.
