tools/litex_json2dts_linux: fix tlb-split 

This is also relevant to vexriscv_smp, not rocket specific.

Fixes these dt-schema validation errors:

cpus: cpu@0: 'tlb-split' is a dependency of 'd-tlb-size'
	from schema : http://devicetree.org/schemas/cpus.yaml#
cpus: cpu@0: 'tlb-split' is a dependency of 'd-tlb-sets'
	from schema : http://devicetree.org/schemas/cpus.yaml#
cpus: cpu@0: 'tlb-split' is a dependency of 'i-tlb-size'
	from schema : http://devicetree.org/schemas/cpus.yaml#
cpus: cpu@0: 'tlb-split' is a dependency of 'i-tlb-sets'
	from schema : http://devicetree.org/schemas/cpus.yaml#
