ARM: omap1: remove unused board files 

All board support that was marked as 'unused' earlier can
now be removed, leaving the five machines that that still
had someone using them in 2022, or that are supported in
qemu.

* cause a problem with level interrupt requests, such as Ethernet. The
* problem occurs when a level interrupt request is asserted while its
* interrupt input is masked in the FPGA, which results in a missed
* interrupt.
*
* In an attempt to workaround the problem with missed interrupts, the
* mask_ack routine for all of the FPGA interrupts has been changed from
* fpga_mask_ack_irq() to fpga_ack_irq() so that the specific FPGA interrupt
* being serviced is left unmasked. We can do this because the FPGA cascade
* interrupt is run with all interrupts masked.
*
* Limited testing indicates that this workaround appears to be effective
* for the smc9194 Ethernet driver used on the Innovator. It should work
* on other FPGA interrupts as well, but any drivers that explicitly mask
* interrupts at the interrupt controller via disable_irq/enable_irq
* could pose a problem.
