Secmon needs a special build rule because of the objcopy -B
operation required to include it in ramstage. Utilize the
manual template so builds continue to work with upcoming
build chnages.
Note: secmon is actually missing symbols still so those
still need to be addressed. That looks to be as if
--gc-sections isn't be honored, but I'm actually thinking
the symbols are just erroneously carried over as the
references for these symbols don't show up in the
symbol table:
U coreboot_build
U coreboot_extra_version
U coreboot_version
U default_baudrate
U lb_add_console
U lb_add_serial
U uart_baudrate_divisor

It also creates file names in the build directory and with
the stage sliced in, but keeps the extension for anything
not .c or .S.
Also some handling for non-.c/.S files was adapted to match.
This is inspired by the commit listed below, but rewritten to match
upstream, and split in smaller pieces to keep intent clear.

Introduce generic-$(type)-ccopts and $(class)-generic-ccopts
to declare compiler flags that apply to all files of a certain
type or of a certain class. Then use them.

The PSCI functionality initially includes CPU_ON and CPU_OFF
functions. Upon entering secmon if the parameters are non-NULL
then a PSCI CPU_ON action is done for the current CPU.
BUG=chrome-os-partner:32112
BRANCH=None
TEST=Booted kernel with PSCI support. Brought up all CPUs in kernel
using PSCI. Turned CPUs on and off.

If an exception is taken that the secmon won't return
to, there needs to be way to reset that cpu's state
w.r.t. stack usage. Therefore, provide secmon_trampoline
which will reinitialize the exception stack and SP_EL0
and start executing with SP_EL0 like the initial state
of the secmon entry.

BRANCH=None
TEST=Built and booted to kernel. Also tested when PSCI
is employed in the kernel.

Two things:
1. Not returning once setting the return state.
2. mempcy(x, y, ARRAY_SIZE(x)) is not memcpy(x, y, sizeof(x))
With these 2 changes arguments and results are being processed
correctly.

In order to process PSCI commands SMC instructions need to be
serviced. Provide a simple way for users of SMC to register their
handlers by function.
The SMC layer hooks into the exception processing, however it only
processes AARCH64 SMC calls. All others are ignored.

BRANCH=None
TEST=Added nop smc call to depthcharge. SMC handled and continue booting

The exception vectors were not reinitialized in secmon yet.
Add that as well as the split BSP vs non-BSP path. In doing
so bring in the cpu.c semantics for determining bsp at runtime.

Secure monitor runs at EL3 and is responsible for jumping to the payload at
specified EL and also to manage features like PSCI.
Adding basic implementation of secure monitor as a rmodule. Currently, it just
jumps to the the payload at current EL. Support for switching el and PSCI will
be added as separate patches.
