[PATCH] miscdevice: introduce builtin_misc_device

[Paul Gortmaker]

This is basically the same as module_misc_device but without the
presence of an exit/remove function.   Similar in nature to the
commit f309d4443130bf814e991f836e919dca22df37ae ("platform_device:
better support builtin boilerplate avoidance").

[I've got several users of this in my local queue; but I'll stagger
 those and this by a merge window to avoid dependency issues.]
