Bin Meng 693b5f6c71 x86: quark: Lock HMBOUND register before jumping to kernel 
When Linux kernel boots, it hangs at:

[    0.829408] Intel Quark side-band driver registered

This happens when Quark kernel Isolated Memory Region (IMR) driver
tries to lock an IMR register to protect kernel's text and rodata
sections. However in order to have IMR function correctly, HMBOUND
register must be locked otherwise the system just hangs.
