fbdev: Remove FBINFO_DEFAULT from framebuffer_alloc()'ed structs

The flag FBINFO_DEFAULT is 0 and has no effect, as struct fbinfo.flags
has been allocated to zero by framebuffer_alloc(). So do not set it.

Flags should signal differences from the default values. After cleaning
up all occurrences of FBINFO_DEFAULT, the token will be removed.

v4:
* clarify commit message (Geert, Dan)
v2:
* fix commit message (Miguel)

fbdev: Add support for the nomodeset kernel parameter

Support the kernel's nomodeset parameter for all PCI-based fbdev
drivers that use aperture helpers to remove other, hardware-agnostic
graphics drivers.

The parameter is a simple way of using the firmware-provided scanout
buffer if the hardware's native driver is broken. The same effect
could be achieved with per-driver options, but the importance of the
graphics output for many users makes a single, unified approach
worthwhile.

With nomodeset specified, the fbdev driver module will not load. This
unifies behavior with similar DRM drivers. In DRM helpers, modules
first check the nomodeset parameter before registering the PCI
driver. As fbdev has no such module helpers, we have to modify each
driver individually.

The name 'nomodeset' is slightly misleading, but has been chosen for
historical reasons. Several drivers implemented it before it became a
general option for DRM. So keeping the existing name was preferred over
introducing a new one.

v2:
* print a warning if a driver does not init (Helge)
* wrap video_firmware_drivers_only() in helper

Remove firmware devices on the PCI bus, by calling

When the kernel is compiled with -Os (CONFIG_CC_OPTIMIZE_FOR_SIZE), tridentfb
hangs the machine upon load with Blade3D cards unless acceleration is disabled.

This is caused by memcpy() which copies data byte-by-byte (rep movsb) when
compiled with -Os. The card does not like that - it requires 32-bit access.

Use iowrite_32() instead.
