Tlspl partitions: 1-6 in both privilege levels, and document kernel-mode tests

Browse Source 
threads/tls/kernel/partition now records the sweep from a kernel module, which settles the range
question the user-mode recording couldn't: privilege changes the permission check, not the range.
Partitions 1, 3 and 4 are ILLEGAL_PERM from user mode and fine from kernel mode, while 7 and up
are ILLEGAL_ARGUMENT either way. So the check goes back to a plain 1-6 for both, and the
kernel-mode carve-out from the last commit - which would have let 8 and 9 through - is gone.

The hardware doc gains a section on kernel-mode tests: what COMMON_KERNEL does, why the stock
crt0 makes a kernel PRX unloadable, which libraries can't be imported, and how much room there
actually is in the kernel partition.
