ec/acpi/ec: replace misleading "recv_ec_data_timeout" console output

In the non-timeout case in recv_ec_data_timeout, a message like this one
will get printed at BIOS_SPEW log level: "recv_ec_data_timeout: 0x00".
The "timeout" part of the function name corresponds to what the function
does, but the message will only be printed when not running into the
timeout which is a bit misleading and might suggest a problem when there
is none. To avoid this possible confusion, don't use the function name
in the printk, but use "Data from EC:" instead.
