Port the initialization sequence necessary for booting the modem remote processor on the MSM8909 SoC from Qualcomm's msm-3.10 release [1]. The sequence is actually similar to the existing one for MSM8996 and MSM8998 except that there is no separate QDSP6SS_MEM_PWR_CTL register and most of the "memories" are enabled at once instead of sequentially. To reuse the existing code just insert some if statements where needed and add a configuration similar to the one from MSM8916.
