This reverts commit ddbfe690e2.
Reason for revert: Causes move cursor movements to be choppy, and device
to be very unresponsive during flashrom EC operations.
Original change's description:
> npcx: workaround the bug that SHM data read via eSPI may be corrupted
>
> In eSPI systems, when the Host performs a data read from the Shared
> Memory space, the returned data may be corrupted. This is a result of
> the Core-to-Host access enable bit being toggled (by toggling CSAE bit
> in SIBCTRL register) during an eSPI transaction.
>
> The workaround in this CL is to set CSAE bit to 1 during initialization
> and remove the toggling of CSAE bit from other EC firmware code.
> (i.e., let the CSAE bit be always 1.)
>
> BRANCH=none
> BUG=none
> TEST=No build errors for make buildall. Flash poppy ec image, make sure
> it can boot to OS. Run "ectool version" over 100000 times, no error
> occurs.
