hw/arm/boot: set CPTR_EL3.ESM and SCR_EL3.EnTP2 when booting Linux with EL3
According to the Linux kernel booting.rst [1], CPTR_EL3.ESM and
SCR_EL3.EnTP2 must be initialized to 1 when EL3 is present and FEAT_SME
is advertised. This has to be taken care of when QEMU boots directly
into the kernel (i.e., "-M virt,secure=on -cpu max -kernel Image").
