Update Linux headers from v5.10.5 to v6.6

This patch imports the Linux kernel from v5.10.5 to v6.6.
Important RISC-V specific changes are:
* hwprobe support
* V support (ptrace and prctl calls)
* KVM support

There are patches on the glibc list that introduce code which uses the
hwprobe interface. Let's update the kernel headers to be ready for these
changes.
