Kévin Redon 9cb8f504cb schematic: mark R15 as no place ...

R15 is pulling VCC_SIM down.
it has probably been added because a load resistor is present in
the FPF2109 datasheet example application, or to not have VCC_SIM
in tri-state.
since we don't read VCC_SIM it is not important to have it in a
defined state.
also the card, phone, or simtrace will provide power to the card
when required (else the card load is high enough to immediately
pull it down).
current flowing from the other card pins back to VCC should not
happen, and if it happens this high value resistor will not have
any effect.

this change has been tested with a real device.
trace and card emulation worked with a Nokia 3310.
