mfd: cros ec: spi: Increase wait time to 200ms
This is a sucky change to bump up the time we'll wait for the EC. Why
is it sucky? If 200ms for a transfer is a common thing it will have a
massively bad impact on keyboard responsiveness.
It still seems like a good idea to do this, though, because we have a
gas gauge that claims that in an extreme case it could stretch the i2c
clock for 144ms. It's not a common case so it shouldn't affect
responsiveness, but it can happen. It's much better to have a single
slow keyboard response than to start returning errors when we don't
have to.
In newer EC designs we should probably implement a virtual battery to
respond to the kernel to insulate the kernel from these types of
issues.
