Kevin O'Connor 60ae92d143 stm32: Disable usb irqs in usbotg handlers 
It appears the usbotg controller can get confused if the usb irq
handler runs while processing a usb request.  Disable usb irqs during
usb processing to avoid this.

Kevin O'Connor 4fa41d9c61 stm32: Rework usbotg transmit interrupts 
Use the XFRC interrupt instead of TXFE.  Don't mask/unmask the tx
interrupts during runtime.  This fixes some race conditions where a tx
notification may have previously gotten lost.

Kevin O'Connor c2a08962b7 spicmds: Rework spi config commands 
Rework the spi_config commands so that bus configuration and shutdown
message configuration is done separately from the main "config_spi"
command.  This makes the spi configuration more flexible.  It's now
possible to use software spi without a CS pin.  It's now possible to
define multiple SPI messages to send on a shutdown event.
