can: mcp251xfd: add dev coredump support
For easier debugging this patch adds dev coredump support to the
driver. A dev coredump is generated in case the chip fails to start or
an error in the interrupt handler is detected.
The dev coredump consists of all chip registers and chip memory, as
well as the driver's internal state of the TEF-, RX- and TX-FIFOs, it
can be analyzed with the mcp251xfd-dump tool of the can-utils:

can: mcp251xfd: rename all user facing strings to mcp251xfd
In [1] Geert noted that the autodetect compatible for the mcp25xxfd driver,
which is "microchip,mcp25xxfd" might be too generic and overlap with upcoming,
but incompatible chips.
In the previous patch the autodetect DT compatbile has been renamed to
"microchip,mcp251xfd", this patch changes all user facing strings from
"mcp25xxfd" to "mcp251xfd" and "MCP25XXFD" to "MCP251XFD", including:
- kconfig symbols
- name of kernel module
- DT and SPI compatible

can: mcp251xfd: rename driver files and subdir to mcp251xfd
In [1] Geert noted that the autodetect compatible for the mcp25xxfd driver,
which is "microchip,mcp25xxfd" might be too generic and overlap with upcoming,
but incompatible chips.
In the previous patch the autodetect DT compatbile has been renamed to
"microchip,mcp251xfd", this patch changes the name of the driver subdir and the
individual files accordinly.
