In case of an invalid pin value bcm2835_pctl_dt_node_to_map()
would leak the pull configs of already assigned pins.
So avoid this by calling the free map function in error case.

This patch is meant to cleanup the exception handling for the paths where
we reset the interrupts and then reconfigure them. In all of these paths
we had very different levels of exception handling. I have updated the
driver so that all of the paths should result in a similar state if we
fail.
Specifically the driver will now unload the mailbox interrupt, free the
queue vectors and MSI-X, and then detach the interface.
In addition for any of the PCIe related resets I have added a check with
the hw_ready function to just make sure the registers are in a readable
state prior to reopening the interface.

Previously, the device tree mapped the FPGA like any other IPs inside
the SoC, but it is actually mapped through the WEIM (Wireless External
Interface Module). This patch updates the device tree to make use of it.
About the timings: in the image provided by the manufacturer, only
CS0GCR1 is changed. The other values are the default ones, but the WEIM
bindings expect them to be all explicitly set in the device tree, so I
just put the default values in the dt.
