mmc: sdhci-msm: Don't enable MMC_CAP2_FULL_PWR_CYCLE

The commit '6e2df8c0e' incorrectly sets this capability.
This needs to be set only if the host is capable of disabling
both vcc and vccq. For SDHCI MSM host controllers only vcc
is disabled during suspend. Hence, remove this capability
for MSM hosts.
