nfctype4: Use correct P2 value for 'Select' commands
The current implementation of the ISO_Select() routine always sets the
P2 value for the 'Select' command to 0. However, according the the NFC
Forum, Type 4 Tag Operation Specification, the value of P2 depends on
what is being selected. The proper values from the specification are
shown below.
Target of Selection P1 P2 Spec Reference
------------------- -- -- --------------
NDEF Tag Application 0x04 0x00 Table 10
Capability Container 0x00 0x0C Table 13
NDEF File 0x00 0x0C Table 19
So, when P1 is 0x04, P2 is 0x00 and when P1 is 0x00, P2 is 0x0C. Add
this logic to the ISO_Select() routine so the proper value for P2 is
always used.
