f1a48eaf0d Add missing file to gpiobus module 
ofw_gpiobus.c is needed when FDT is used.

193d9e768b sys/modules: normalize .CURDIR-relative paths to SRCTOP 
This simplifies make output/logic

Tested with:	`cd sys/modules; make ALL_MODULES=` on amd64

aabc5ce043 Refactor FDT part of gpioled driver 
- Split driver in two parts: FDT and non-FDT
- Instead of reattach gpioled nodes to GPIO bus use
    gpio_pin_get_by_ofw_idx and add ofwbus and simplebus as parrent buses

99819ca00c When building modules, define make variable OPT_FDT if the kernel config 
includes the FDT option.  Use OPT_FDT to conditionally compile modules
that require FDT support.

In the past we've gotten away with using the arch name as a proxy for FDT
support in makefile conditional logic, but now mips has some platforms with
fdt support and some without and we need a more direct test.

128e3872b9 Add a PPS driver that takes the timing pulse from a gpio pin. Currently 
supports only ofw/fdt systems.  Some day, hinted attachment for non-fdt
systems should be possible too.

9e1252ae20 Revert r299739. That did not make it better. 
Instead disconnect gpiokeys from the build until it's fixed and buildable;
the SUBDIR list was not ordered properly anyway ;-)

1dd2aa86b9 Fix the build of gpiobus as a module. 
Add the missing newbus interfaces and gpioc, which is part of basic gpiobus
framework.

3cf391a131 Allow building the GPIO bus and associated bits as modules. 
This is primarily done to save a few bytes here and there on embedded
systems with limited flash space for kernels - a very limited (sub-1MB)
space may be available for the kernel and may only support gzip encoding.
The rootfs can be LZMA compressed.
