[PATCH 2/2] target/riscv: Make CPU config error handling generous (sifive_e/u/opentitan)

[Tsukasa OI]

If specified CPU configuration is not valid, not just it prints error
message, it aborts and generates core dumps (depends on the operating
system).  This kind of error handling should be used only when a serious
runtime error occurs.

This commit makes error handling on CPU configuration more generous on
sifive_e/u and opentitan machines.  It now just prints error message and
quits (without coredumps and aborts).

This is separate from spike/virt because it involves different type
(TYPE_RISCV_HART_ARRAY) on sifive_e/u and opentitan machines.
