loongarch/kexec: refactor for kernel/Kconfig.kexec 

The kexec and crash kernel options are provided in the common
kernel/Kconfig.kexec. Utilize the common options and provide
the ARCH_SUPPORTS_ and ARCH_SELECTS_ entries to recreate the
equivalent set of KEXEC and CRASH options.

	  kexec is a system call that implements the ability to shutdown your

	  current kernel, and to start another kernel.  It is like a reboot

	  but it is independent of the system firmware.   And like a reboot

	  you can start any kernel with it, not just Linux.

	  The name comes from the similarity to the exec system call.

	  Generate crash dump after being started by kexec. This should

	  be normally only set in special crash dump kernels which are

	  loaded in the main kernel with kexec-tools into a specially

	  reserved region and then later executed after a crash by

	  kdump/kexec.
