OMAP3 SDRC: Fix freeze when scaling CORE dpll to < 83Mhz
OMAP3 SDRC: Fix freeze when scaling CORE dpll to < 83Mhz

This patch fixes a bug in the CORE dpll scaling sequence which was
errouneously clearing some bits in the SDRC DLLA CTRL register and
hence causing a freeze.  The issue was observed only on platforms
which scale CORE dpll to < 83Mhz and hence program the DLL in fixed
delay mode.

Issue reported by Limei Wang <c7357d5a37b479e07a2a1c31a97226df64894eba@motorola.com>, with debugging
assistance from Richard Woodruff <d8b9d570e15139334144aba9361d2590e55fc625@ti.com> and Girish
