[LEDE-DEV] [PATCH] kirkwood: Add RTC driver to kernel for working hctosys

[p.wassi at gmx.at]

From: Paul Wassi <p.wassi at gmx.at>

Build the RTC driver into the kernel, (and remove the optional module), in order
to make hctosys working. (Currently the module is loaded after hctosys has failed previously)

It's the same on kirkwood, as it is on imx6 here:
https://patchwork.ozlabs.org/patch/683889/

hctosys fails due to missing RTC driver; the module providing the driver is
loaded too late. Integrating the driver into the kernel resolves this.
Additionally, the afterwards unnecessary kmod-RTC-driver is remove from the image.

As a result, the bootlog from a Seagate Dockstar looks like this:
> [    0.958105] rtc-mv f1010300.rtc: rtc core: registered f1010300.rtc as rtc0
> (...)
> [    1.500257] rtc-mv f1010300.rtc: setting system clock to 2016-10-23 11:57:18 UTC (1477223838)
