CONFIG_USB_IMX21_HCD should be handled in generic config and
module package. So moved it into generic config.
This also fixed build issue (kernel config question) of layerscape
armv8_32b since it also used ARCH_MXC.

Following errors were seen in the past on imx6 when using serial:
[ 22.617622] imx-uart 2020000.serial: DMA transaction error.
[ 22.623228] imx-uart 2020000.serial: DMA transaction error.
[ 22.628826] imx-uart 2020000.serial: DMA transaction error.
[ 22.648951] imx-uart 2020000.serial: DMA transaction error.
[ 22.654558] imx-uart 2020000.serial: DMA transaction error.
[ 22.660156] imx-uart 2020000.serial: DMA transaction error.
Which is the reason why DMA for the serial ports
got disabled in commits:
efb362cd93 ("imx6: disable dma on uart")
3b4241071d ("imx6: disable UART dma")
As indicated on mailinglist discussion, the cause seems to be
the usage of very old SDMA firmware which is present in the soc:
[ 0.624302] imx-sdma 20ec000.sdma: Direct firmware load for imx/sdma/sdma-imx6q.bin failed with error -2
[ 0.624318] imx-sdma 20ec000.sdma: Falling back to user helper
[ 64.531607] imx-sdma 20ec000.sdma: external firmware not found, using ROM firmware
This patch adds the new firmware binary. (2196 bytes)
It is required to embed the binary into the kernel image, as it
gets loaded very early in the boot process where the rootfs is not
available yet:
[ 0.622966] imx-sdma 20ec000.sdma: loaded firmware 3.3
Extended testing shows that the DMA errors are not seen anymore
when using this newer firmware version.

The IMX6 PCIe host controller does not fire legacy interrupts if MSI is
enabled. A patch is being worked on to enable MSI at runtime only when
it is needed but meanwhile this patch will disable MSI for the imx6 kernel.
This fixes the no interrupt issue on cards/drivers that use legacy interrupts
such as ath9k.

HAMRADIO enabled in all generic configs, but no one platform directly
use related drivers/protocols. This symbol is only used for kmod-ax25
package modules. Furthermore, half of platforms explicitly disables
this symbol, what silently disables build of modules for kmod-ax25
package.
So disable HAMRADIO by-default in generic config, add it to kmod-ax25
package and remove it from platform specific configs.

The OpenWrt build system uses MACHINE_FEATURES of fpu to set the HAS_FPU which
in turn sets the default of CONFIG_SOFT_FLOAT as well as uClibc configuration.
As the IMX6 SoC has both vfpv3 and NEON hardware support we want to add fpu
to the feature list. This will default the IMX6 target to use -mfloat-abi=hard
which will the be most efficient use of floating point.
When switching to hard float, we also need to enable VFP support in the kernel.
