target-arm: Implement AArch64 OSLAR/OSLSR_EL1 sysregs
Added oslar_write function to OSLAR_EL1 sysreg, using a status variable in ARMCPUState.cp15 struct (oslsr_el1). This variable is also linked to the newly added read-only OSLSR_EL1 register. Linux reads from this register during its suspend/resume procedure.
