mapping.py: bugfix in netbsd device tree generation

During Frame Buffer and Xicu instantiation, it exists only one argument (periph.arg): In the case of the Xicu, this argument corresponds to the HWI, PTI and WTI count, in the case of the Frame Buffer it correspondes to the WIDTH and HEIGHT.

10	# This file contains the classes required to define a mapping for the GIET_VM.
11	# - A 'Mapping' contains a set of 'Cluster' (hardware architecture)
12	# a set of 'Vseg' (kernel virtual segments mapping)
13	# a set of 'Vspace' (several user applications).
14	# - A 'Cluster' contains a set of 'Pseg' (all physical segments in cluster)
15	# a set of 'Proc' (processors in cluster)
16	# a set of 'Periph' (peripherals in cluster)
17	# a set of 'Coproc' (coprocessors in cluster)
18	# - A 'Vspace' contains a set of 'Vseg' (user virtual segments mapping)
19	# a set of 'Task' (user tasks mapping)
20	# - A 'Vseg' contains a set of 'Vobj'
21	# - A 'Periph' contains a set of 'Irq' (only for XCU, ICU and PIC types )
22	# - A 'Coproc' contains a set of 'Cpports' (one port per MWMR channel)
23	##########################################################################################
24	# Implementation Note
25	# As described above, the various objects are distributed in the PYTHON structure:
26	# For example the psegs set is split in several subsets (one subset per cluster),
27	# or the tasks set is split in several subsets (one subset per vspace), etc...
28	# In the C binary data structure used by the giet_vm, all objects of same type
29	# are stored in a linear array (one single array for all psegs for example).
30	# For all objects, we compute and store in the PYTHON object itsel a "global index"
31	# corresponding to the index in this global array, and this index can be used as
32	# a pseudo-pointer to identify a specific object of a given type.
