Touch Wake : bump to v1.1a (Yank555.lu)

- fixed touch wake disbaled as soon as proxy sensor was enabled, no matter if proximity was detected or not (my derp, introduced in 1.1)
- fixed proximity state change detection (is in cm36651.c, not ssp_input.c, which is not compiled for i9300)
- removed "off hook" detection, it was relying on a constant (PSTN_ON_HOOK, defined in telephony.h), so made no sense to keep it
