mn10300: defconfig: cleanup from old Kconfig options

Remove old, dead Kconfig options (in order appearing in this commit):
 - EXPERIMENTAL is gone since v3.9;
 - INET_LRO: commit c1dcd06bd900 ("ipv4: Remove inet_lro library");
 - MTD_PARTITIONS: commit 1faf3d2d3b5f ("mtd: kill
   CONFIG_MTD_PARTITIONS");
 - MTD_CHAR: commit 94578ee33738 ("mtd: merge mtdchar module with
   mtdcore");
 - NETDEV_1000 and NETDEV_10000: commit 7d63538a9c61 ("drivers/net:
   Kconfig and Makefile cleanup"); NET_ETHERNET should be replaced with
   just ETHERNET but that is separate change;
 - HID_SUPPORT: commit cbe72d6c6ddf ("HID: Fix the generic Kconfig
   options");
 - RCU_CPU_STALL_DETECTOR: commit ccf42a898130 ("rcu: Remove conditional
   compilation for RCU CPU stall warnings");
