Update MIPS email addresses MIPS will soon not be a part of Imagination Technologies, and as such many @imgtec.com email addresses will no longer be valid. This patch updates the addresses for those who: - Have 10 or more patches in mainline authored using an @imgtec.com email address, or any patches dated within the past year. - Are still with Imagination but leaving as part of the MIPS business unit, as determined from an internal email address list. - Haven't already updated their email address (ie. JamesH) or expressed a desire to be excluded (ie. Maciej). - Acked v2 or earlier of this patch, which leaves Deng-Cheng, Matt & myself. New addresses are of the form firstname.lastname@mips.com, and all verified against an internal email address list. An entry is added to .mailmap for each person such that get_maintainer.pl will report the new addresses rather than @imgtec.com addresses which will soon be dead. Instances of the affected addresses throughout the tree are then mechanically replaced with the new @mips.com address.

clk: Ingenic: Adjust cgu code to make it compatible with X1830. The PLL of X1830 Soc from Ingenic has been greatly changed, the bypass control is placed in another register, so now two registers may needed to control the PLL. To this end, a new "bypass_reg" was introduced. In addition, when calculating rate, the PLL of X1830 introduced an extra 2x multiplier, so a new "rate_multiplier" was introduced. And adjust the code in jz47xx-cgu.c and x1000-cgu.c, make it to be compatible with the new cgu code.

clk: Ingenic: Adjust cgu code to make it compatible with X1830. The PLL of X1830 Soc from Ingenic has been greatly changed, the bypass control is placed in another register, so now two registers may needed to control the PLL. To this end, a new "bypass_reg" was introduced. In addition, when calculating rate, the PLL of X1830 introduced an extra 2x multiplier, so a new "rate_multiplier" was introduced. And adjust the code in jz47xx-cgu.c and x1000-cgu.c, make it to be compatible with the new cgu code.
