fix order of eip activation

[yihuang]

Closes: #287

Description

Remove the extra eips since we already activated Berlin hardfork in chain config.

Why wrong order cause issue:

• eip1884 set SLOAD's constant gas to 800, without touch dynamic gas
• eip2929 change SLOAD to use dynamic gas(2100 for cold access) and set constant gas to zero

So in the right order, the end result is 2100, but in reverse order, we get 2900.

Verified in external integration test.
