Adapt InDeselect & InRelease to RC-S360
nfc-list now supports discovery of several typeA tags properly

Current status of RC-S360 support is:
    - nfc-list          => ok except for B' & 3B
    - nfc-anticol       => fails to send raw frames before select
    - nfc-mfultralight  => ok
    - nfc-mfclassic     => ok
    - pn53x-tamashell   => ok
    - pn53x-diagnose    => ok
    - nfc-dep-initiator => ok
    - nfc-dep-target    => fails in InitAsTarget
    - nfc-emulate-*     => fails in InitAsTarget

Commands momentarily disabled for RC-S360:
    - select_passive_target for B'& 3B
