espi flash read returns invalid data if the read length is more than 0xFFFA bytes, it supports maximum transaction of 2^16 bytes at a time, resister spcom[TRANLEN] is 16 bits. If the transaction length is greater than 0xFFFF, it need to be split into multiple transactions.

changes for v2: fix some compile warnings. remove ifdef and use if else instead.
changes for v3: rebased on first patch.
[Xie Shaohui] This patch is not needed any more; I have merged it to previous patch and resend it as v4.
