printk: reduce LOG_BUF_SHIFT range for H8300

BugLink: https://bugs.launchpad.net/bugs/1904450
[ Upstream commit 550c10d28d21bd82a8bb48debbb27e6ed53262f6 ]

The .bss section for the h8300 is relatively small. A value of
CONFIG_LOG_BUF_SHIFT that is larger than 19 will create a static
printk ringbuffer that is too large. Limit the range appropriately
for the H8300.
