On non-LPC platforms (such as those using I2C or SPI for EC comms),
the EC memory map is not directly accessible via memory-mapped I/O.
Instead, these platforms must use the EC_CMD_READ_MEMMAP host command
to retrieve system information.
Implement google_chromeec_get_switches() using this host command for
non-LPC systems. This enables get_lid_switch() to function correctly
on eSPI-based and other non-LPC mainboards, allowing them to support
lid-controlled logic.
BUG=none
TEST=Verify the LID state using get_lid_switch() on Google/Quartz.
