Changes

Switch tests that use uvm_plain and other tests manually setting to 5.10 to use 6.1

Reason

These tests don't care about the underlying kernel. Move them to the latest (and most widely used) one.

LGTM overall. One small thing not directly related to your changes

kinda unrelated, but I think we have a fixture for 6.1 debug kernel. Could we use that instead of this?

Use the existing guest_kernel_6_1_debug fixture instead of manually
constructing the debug kernel path from the kernel fixture.

Signed-off-by: Riccardo Mancini <mancio@amazon.com>
Introduce a new fixture used by tests that don't care about the kernel
version.
This will make it easier to switch the default version in the next
commits.

Signed-off-by: Riccardo Mancini <mancio@amazon.com>
Alias guest_kernel_6_1_debug as guest_kernel_default_debug and update
uvm_plain_debug and test_gdb to use it.

Signed-off-by: Riccardo Mancini <mancio@amazon.com>
We expect most customers to use 6.1 rather than 5.10 nowadays.

Signed-off-by: Riccardo Mancini <mancio@amazon.com>
As now uvm_plain is 6.1, drop uvm_plain_6_1 and use uvm_plain directly
in those tests.
No changes to the tests.
