So far only the 240 Ohm to 34 Ohm table was available. Because the constants used have speaking names it can be confusing to use e.g. PAD_CTL_DSE_48ohm when according to the reference manual 52 Ohm is the correct value. This patch adds the 260 Ohm to 37 Ohm table. For example, the IOMUXC_SW_PAD_CTL_PAD_SD2_CLK register (SD-card clock) uses the added table.
