fc171fe539 drivers: Fix bus->match for Linux v6.11
In Linux v6.11, the 'bus_type' structure match() callback was updated to
make its 'drv' argument constant. Add a conftest test to detect this and
update the relevant drivers according to fix building them for Linux
v6.11.

VADDR via iosys_map structure. Use the proper iosys map
utils to pass address when doing the tegra_ivc_init().

02d724565b platform: tegra: rtcpu: Use conftest
Instead of relying on kernel version to determine if the 'remove'
callback for the 'bus_type' structure return an integer or void, add a
compile time test to the conftest.sh script to determine this at compile
time for the kernel being used. This is beneficial for working with 3rd
party Linux kernels that may have back-ported upstream changes into
their kernel and so the kernel version checks do not work.

d20bc7c188 platform: tegra: rtcpu: Combine drivers
The RTCPU driver has a dependency of the following kernel modules:

 clk-group
 device-group
 reset-group

Rather that builds all these source files as individual drivers, which
is bloating the number of kernel modules required, compile these source
files into the main RTCPU kernel module.

Finally, remove any unneeded header files from the ivc-bus driver.

and not void. Make the necessary changes to allow the RTCPU driver to
