meta: update mohonpeak.cfg for SATA, SMBus, LPC, WDT, crypto & highmem64g

Update mohonpeak.cfg to enable SMBus & iSMT driver, crypto framework,
LPC, watchdog-timer & >4G memory for 32-bit build. The update is possible
due to recent  merge of LTS/LTSI commits available since 3.4.74.

Remove CONFIG_PATA_SCH because pata_sch.c only supports Intel SCH IDE
PCI ID(0x811A) and not Rangeley/Avoton IDE PCI ID(0x1C02). To enable
SATA AHCI, CONFIG_SATA_AHCI is turned now because of upstream commit-ID
29e674dd5c8e781589f09c3ee139c80f6da274e4 has been merged into
linux-yocto. On Mohonpeak platform, there are only SATA ports and
not PATA.
