Subject: [PATCHv2 0/2] SBS battery PEC support

Hi,

Second try to enable PEC for SBS battery. Mainline currently
has 3 different platforms using sbs-battery with an I2C driver
not implementing I2C_M_RECV_LEN:

 * i2c-exynos5
 * i2c-rk3x
 * i2c-tegra

On those platforms PEC will be temporarly disabled for SBS
functions requesting strings. I considered moving the emulation
to I2C core, but it's specific to the SBS battery. The hack
only works because the strings are constant.

Changes since PATCHv1:
 * dropped all applied changes
 * rebased on top of power-supply's for-next branch
 * keep existing string reading method as fallback
