bus: mhi: host: Use mhi_soc_reset() API in place of register write

Browse Source 
Currently, a direct register write is used when ramdump collection
in panic path occurs. Replace that with new mhi_soc_reset() API
such that a controller defined reset() function is exercised if
one is present and the regular SOC reset is done if it is not.
