lenovo/g505s: fix the IRQs and create the good MP tables

IRQ programming should be outside the obsolete MP table generation,
just like the proper way done for asus/am1i-a AMD fam16h - closest
example for Lenovo G505S: all the fam15h boards have these "bad IRQs".
OS like Linux still finds a way, but Kolibri can't see the IRQ table -
so we need to fix the interrupts. Also, CB:38313 dropped the broken MP
tables for many boards including g505s - so we can make the good ones.

With this change applied:
* G505S boots fine to Linux - no angry IRQ-related messages at dmesg;
* KolibriOS sees 18 IRQs in a table and could successfully attach a
driver to Atheros QCA8172 onboard Ethernet controller with an IRQ 3.
