ram: ast2600: Fix incorrect statement of the register polling
The condition "~data" in the if-statement is a typo. The original
intention is to poll if SDRAM_PHYCTRL0_INIT bit equals to 0. So use
"data == 0" for instead.
Besides, the bit[1] of "phy_status" register is hardwired to
SDRAM_PHYCTRL0_INIT (with inverse logic). Since SDRAM_PHYCTRL0_INIT has
already done, remove the unnecessary checking of phy_status[1].
