1. A lubricant feed method for feeding a turbomachine with lubricant, said turbomachine having at least a first set of bearings and a second set of bearings, both the first and the second set being fed with lubricant, and the second set of bearings operating at a bearing temperature that is higher than a bearing temperature of the first set, the method comprising a step of heating a lubricant flow upstream from the second set of bearings by exchanging heat with a flow of lubricant returning from the second set of bearings, so that the second set of bearings is fed with lubricant at a lubricant temperature that is higher than a lubricant temperature of lubricant fed to the first set of bearings. 2. The lubricant feed method according to claim 1, further comprising a step of cooling a flow of lubricant in a heat exchanger upstream from the first set of bearings. 3. The lubricant feed method according to claim 1, wherein the first set of bearings is fed with lubricant by a first circuit, and the second set of bearings is fed with lubricant by a second circuit branching from the first circuit. 4.

The lubricant feed device according to claim 4, wherein the first circuit includes a heat exchanger between said branch point and the first set of bearings in order to cool a flow of lubricant for the first set of bearings. 6. A turbomachine comprising a first set of bearings, a second set of bearings operating at a temperature higher than the first set of bearings, and a lubricant feed device comprising a first circuit for feeding lubricant to the first set of bearings, and a second circuit for feeding lubricant to the second set of bearings, the first circuit having a branch point leading to the second circuit, and the second circuit having a heat exchanger for transmitting heat from at least a flow of lubricant returning from the second set of bearings to a flow of lubricant for feeding the second set of bearings, so as to feed the second set of bearings with lubricant at a lubricant temperature that is higher than a lubricant temperature of lubricant fed to the first set of bearings. 7. The turbomachine according to claim 6, wherein the first circuit includes a heat exchanger between said branch point and the first set of bearings in order to cool a flow of lubricant for the first set of bearings. 8. A turbine engine assembly, or a turbine engine assembly for aviation purposes, including a turbomachine comprising a first set of bearings, a second set of bearings operating at a temperature higher than the first set of bearings, and a lubricant feed device comprising a first circuit for feeding lubricant to the first set of bearings, and a second circuit for feeding lubricant to the second set of bearings, the first circuit having a branch point leading to the second circuit, and the second circuit having a heat exchanger for transmitting heat from at least a flow of lubricant returning from the second set of bearings to a flow of lubricant for feeding the second set of bearings, so as to feed the second set of bearings with lubricant at a lubricant temperature that is higher than a lubricant temperature of lubricant fed to the first set of bearings. 9. The turbine engine assembly according to claim 8, wherein the first circuit includes a heat exchanger between said branch point and the first set of bearings in order to cool a flow of lubricant for the first set of bearings.
