ARM: dts: msm: Limit UFS spm level to 3 on Shima 

Hynix UFS2.2 is drawing 40mA current during APPS PC. This issue is
seen only if PX10 is turned off and Vccq2 is ON. Since Vccq2 is
always-on supply we can't turn it off. So don't turn off PX10, 
by updating spm_lvl to 3.

In sleep state (spm-lvl=3) its drawing only .5mA.
