omap: sram: fix is_sram_locked check
For OMAP24xx/34xx/44xx: omap_type() returns the correct type:
OMAP2_DEVICE_TYPE_TEST
OMAP2_DEVICE_TYPE_EMU
OMAP2_DEVICE_TYPE_SEC
OMAP2_DEVICE_TYPE_GP
OMAP2_DEVICE_TYPE_BAD
In current implementation there are two problems:
Problem 1:
For 34xx, the current if check will never return true.
Problem 2:
For 24xx the correct type check should be with omap_type() function
Verified by checking the TRM 24xx for CONTROL_STATUS register bits
