Randall Spangler 9de183a5d6 rambi: Add 7 ms delay before turning off PP3300_DX at shutdown ...

This works around an issue where LCDVCC falls too slowly.  The impact
is to slow shutdown by 7 ms, which isn't noticeable to the user.

BUG=chrome-os-partner:26561
BRANCH=rambi
TEST=shut down rambi; still shuts down, and ~7 ms more time is spent
     in S0->S3 state.

     before:
	[429.933010 power state 3 = S0, in 0x043f]
	[429.933240 power state 7 = S0->S3, in 0x043f]
	[429.933614 power state 2 = S3, in 0x042b]
	[429.934013 power state 8 = S3->S5, in 0x0428]
     after:
	[20.355975 power state 3 = S0, in 0x003f]
	[20.356194 power state 7 = S0->S3, in 0x003f]
	[20.363957 power state 2 = S3, in 0x002c]
	[20.364179 power state 8 = S3->S5, in 0x002c]
	[20.364877 power state 1 = S5, in 0x0008]
