ec/google/chromeec: Add option to control reading long battery strings
Older ChromeOS devices (pre-CR50) do not support reading long battery strings. This commit adds a Kconfig option, EC_GOOGLE_CHROMEEC_READ_BATTERY_LONG_STRING, to enable or disable this feature. This allows devices with TPM_GOOGLE (CR50/TI50) to read and display long battery strings, while older devices like google/link, wolf, samus, and chell will continue to display only the first 8 characters. This change ensures compatibility with older devices while enabling the display of complete battery information on newer platforms. BUG=b:366338622 TEST=Verified on google/tivviks_ufs: * Long battery string is displayed when EC_GOOGLE_CHROMEEC_READ_BATTERY_LONG_STRING is enabled. * Short battery string is displayed when EC_GOOGLE_CHROMEEC_READ_BATTERY_LONG_STRING=n.
