config: yoshino: Switch from HZ_100 to HZ_300

300 Hz is a good compromise choice allowing server performance while also showing good interactive responsiveness even on SMP and NUMA systems and exactly dividing by both PAL and NTSC frame rates for video and multimedia work.

100 Hz is a typical choice for servers, SMP and NUMA systems with lots of processors that may show reduced performance if too many timer interrupts are occurring.
