The IRQF_DISABLED is a NOOP and scheduled to be removed. According to
commit e58aa3d2d0cc ("genirq: Run irq handlers with interrupts
disabled") running IRQ handlers with interrupts enabled can cause stack
overflows when the interrupt line of the issuing device is still active.
This patch removes using this deprecated flag and additionally removes
redundantly setting IRQF_SHARED for isp1760_udc_register().

The isp1760 driver registration function returns an error if USB is
disabled. This made sense when the driver only supported host
controllers, but now that it supports peripheral controllers host
support isn't mandatory anymore.
Fix this by returning an error only when both the HCD and UDC functions
are disabled, either through the kernel configuration or at runtime.

Now that this is DRD, it doesn't make sense to keep it under
drivers/usb/host.
