[Skiboot] [PATCH 1/6] FSP/ELOG: Reduce elog read buffer size

[Vasant Hegde]

Presently we are allocating 256K for elog read buffer. But we just
read one log at a time. Also maximum size of ELOG is 16KB.

Effectively we are not using remaining 240K. This patch reduces
the size of the buffer to 16K.
