pch_gbe: Fix build error by selecting all the possible dependencies.

Fengguang reported a kernel build failure as following: drivers/built-in.o: In function `pch_gbe_ioctl': pch_gbe_main.c:(.text+0x510370): undefined reference to `pch_ch_control_write' pch_gbe_main.c:(.text+0x510393): undefined reference to `pch_ch_control_write' pch_gbe_main.c:(.text+0x5103b3): undefined reference to `pch_ch_control_write' ... It's a regression by commit da15864. The root cause is that the CONFIG_PPS is not set there, consequently CONFIG_PTP_1588_CLOCK can not be set anyway, which finally causes ptp_pch and pch_gbe_main build failures. As David prefers to use *select* to fix such module co-dependency issues, this patch explicitly selects all the possible dependencies of PCH_PTP.
