sysmo: fix dyn TS: Revert "Activate PTCCH UL" [in sysmobts]

This reverts commit 53d792c3b027bfb42d77804e3e687a287e122ef3.
See http://osmocom.org/issues/1796

The commit caused this error for PDCH TS with SysmoBTS:

DL1P <0007> l1_if.c:164 Tx L1 prim MPH-ACTIVATE.req
DL1C <0006> oml.c:811 Error activating L1 SAPI PTCCH on TS 7: Invalid parameter
DL1C <0006> oml.c:1089 (bts=0,trx=0,ts=7,ss=0) act failed mark broken due status: -4

Plain PDCH TS show this error but continue to function despite the SAPI
activation failure.

As a side effect, the SAPI activation failure breaks dynamic TS. GPRS
initially works, but the broken status prevents transitions to TCH/* modes
in the BSC:

DRLL <0000> chan_alloc.c:355 Failed to allocate TCH_H channel
DRSL <0004> abis_rsl.c:1656 BTS 0 CHAN RQD: no resources for TCH_H 0x45

Since the commit only enabled PTCCH UL in sysmobts, no other BTS models are
affected. Notice that lc15 still has PTCCH UL disabled all the while, before
and after this commit and its revert.

Also note that PTCCH DL is and has been enabled without problems (see
further above in sapi_dir_pdtch_sapis[]). This is only about PTCCH UL.
